Teacher: Now, understand the problem? Solve this instance: NEW YORK (AP) — If Jimmy Fallon had already proven he was a natural hosting NBC's "Late Night," he left no doubt Monday that "The Tonight Show" now fits him like a glove.

 As promised during the much-promoted run-up to his "Tonight Show" debut, Fallon made no drastic changes to the "Late Night" formula that had served him for five years. He remained funny, gracious, bubbly and, above all, comfortable presiding over a show that was different mostly for its earlier time slot, its classier production values and legendary brand name. 
  
 "We can book people from the West Coast?!" he joked at his newfound status. 
  
 He did pretty well with his bookings on opening night: Will Smith and the rock group U2. 
  
 But all that was ahead. 
  
 First, his viewers beheld his new set, boasting burnished-wood paneling and panoramic blue curtains. 
  
 They had seen his filmed opening — Jimmy as the New York nightcrawler — shot by director Spike Lee. 
  
 They discovered that his band, the Roots, had grown by two from its already husky eight pieces. 
  
 Then out he came, to thunderous applause, and planted himself on his mark (a four-leaf clover) to deliver his first monologue. 
  
 "I'm Jimmy Fallon," he began, and, with a nod to past late-night turbulence that most recently saw his "Tonight" predecessor, Jay Leno, make an unsought exit, he added, "I'll be your host — for now." 
  
 He expressed gratitude for his new gig, introduced his parents in the studio audience, and dispensed love in every direction — and made it sound authentic. 
  
 He had a few Olympics jokes, one offering sympathy to NBC sportscaster Bob Costas, who was sidelined from several days of Olympics coverage with a blinding bout of pinkeye. 
  
 "You could tell he was having trouble when he spent half-an-hour interviewing a mop he thought was Shaun White," Fallon cracked. 
  
 Back at his desk, he voiced what seemed like an aside: "To my buddy who said that I'd never be the host of 'The Tonight Show' — and you know who you are — you owe me a hundred bucks, buddy." 
  
 With that, Robert De Niro burst through the curtain and plunked a hundred dollars on Fallon's desk. 
  
 But that wasn't all. In rapid succession, a parade of other celebs circled through right behind him. They included Joe Namath, Rudolph Giuliani, Lindsay Lohan, Lady Gaga, Mike Tyson, Stephen Colbert and Sarah Jessica Parker. 
  
 Joan Rivers was also among them, repaying her "debt" and making a bit of history in the bargain: 49 years earlier to the day, the veteran comedian had made her first appearance on "The Tonight Show Starring Johnny Carson" in that very studio, and had not appeared on "Tonight" since 1987, when she was banned by Carson after jumping to Fox to host her own short-lived show. 
  
 A key part of the celebratory spirit for Fallon was the fact that, after more than 40 years in Los Angeles, he and NBC have brought "Tonight" back to New York and Rockefeller Plaza, where it has reclaimed Studio 6B, once the home of Carson and, before him, "Tonight" host Jack Paar. 
  
 If viewers needed visual evidence of "Tonight's" restored New York state of mind, Fallon delivered it with flourish. 
  
 From the observation deck atop the G.E Building he occupies, he introduced U2, who, 70 stories aloft, performed a new song, "Invisible," against a magnificent New York cityscape at a perfect moment of dusk. The backdrop was so beautiful you might have sworn it was computer generated, but it was real, as was the bitter cold that had the musicians, and a legion of fans gathered round, clad in heavy winter wear. 
  
 But after a commercial break, Fallon and his musical guests were cozy, back in the studio, where U2, seated on the powder-blue couch, performed an acoustic version of their Oscar-nominated song, "Ordinary Love." 
  
 It was a fine ending to a much-assured hour. 
  
 "I just want to do the best I can and take care of this show for a while," Fallon told viewers. "If you guys let me stick around long enough, maybe I'll get the hang of it." 
  
 No worries. For five years on "Late Night" he was getting the hang of it.

 What a nice young man. 
  
  
  
  
  
  
  
  
  
 Jimmy Fallon, the new host of “The Tonight Show,” introduced himself to viewers on Monday like a freshly licensed doctor taking over a retiring gerontologist’s practice. 
  
 Mr. Fallon didn’t smirk or make sarcastic asides. He gently and earnestly explained that he is 39, lives in New York City and has a wife and a new baby. He pointed out his parents in the studio audience and also how the monologue works. He choked up a little when talking about “The Tonight Show” legacy. “I just want to do the best I can,” he said. “And take care of the show for a while.” 
  
 Even with celebrity cameos (Tina Fey, Stephen Colbert, Robert De Niro, among many others) and high-profile guests like Will Smith and the band U2, Mr. Fallon’s debut was more sweet than sassy. He was the grateful heir, the eager freshman, the class clown with top grades and a good heart, someone older viewers can embrace without fear of being mocked or overlooked. 
  
 And that was interesting, because the most fateful generational shift isn’t between baby boomers who were loyal to Jay Leno, the previous “Tonight” host, and younger viewers who are more comfortable with Mr. Fallon, a “Saturday Night Live” alumnus who incorporated tweets and Internet skits when he took over “Late Night” in 2009. Now it’s “Tonight” vs. tomorrow: This old-fashioned kind of programming is at the mercy of a changing landscape where audiences are balkanized, and viewing habits are radically altered. 
  
 The “Tonight” show on NBC is in good hands, but its longevity rests less on the host than on audiences who increasingly don’t turn on a television to watch television. Mr. Fallon intimated as much when he recalled begging his parents to let him stay up late to watch Johnny Carson. He got a little emotional when he added that he hoped there was “a kid out there asking their parents to stay up to watch me.” 
  
 Maybe. But that kid can watch “Tonight” on his iPhone on the school bus the next day. And unlike Mr. Fallon, he isn’t likely to grow up aspiring to host the “Tonight” show, any more than he will get his news from a paper edition of The New York Times. 
  
 Paradoxically, a format that hasn’t changed since Mr. Carson codified it (monologue, celebrity, musical guest), is ideally constituted for the cut-and-paste ethos of YouTube and Twitter. Far more than a drama or a reality show, a joke or musical number can be plucked and posted online as a stand-alone. There is no need to DVR: Why record the cow when the Internet and social media can give viewers the milk free? 
  
 And that sense of impending change tends to arouse the instinct to preserve, which may be why Mr. Fallon’s first “Tonight” show was so steeped in tradition and solemnity. 
  
 After more than 40 years in Los Angeles, the show has moved back to New York, where it originated in 1954. Spike Lee was asked to film the show’s artsy opening credits. Even the title has reverted to the wording that Mr. Carson used. When Mr. Leno took over the show in 1992, he changed it to “The Tonight Show With Jay Leno.” Mr. Fallon is calling his “The Tonight Show Starring Jimmy Fallon.”

 The new set is more elegant than Mr. Leno’s, but also quite formal and a little impersonal: a slate blue couch, a handsome honey-colored wood desk and matching walls. The one feature that distinguishes it from a business center at a Four Seasons hotel is the backdrop: a New York skyline made of miniature wooden skyscrapers. (Mr. Fallon also had a four-leaf clover painted on the floor to mark his place for the monologue.) 
  
 The changeover was commemorated with a visually stunning novelty: U2 performed a new song, “Invisible,” on the roof of Rockefeller Center, framed by the pink and gold of Manhattan’s skyline at sundown. 
  
 Mr. Fallon delivered a fairly classic “Tonight” monologue with predictable jokes about the Olympics. He also introduced a staple of his “Late Night” repertory, a dance number. He and Mr. Smith donned denim overalls and performed “The Evolution of Hip-Hop Dancing.” 
  
 But throughout the show, Mr. Fallon made nice more than he made jokes. It was notable that when he brought up thank you notes, he wasn’t introducing his popular letter-writing skit. Instead, he congratulated Mr. Smith on the good manners of his daughter, Willow, 13, marveling that after he sang one of her songs a few years ago, Willow wrote him a polite thank you letter on proper stationery. 
  
 Mr. Fallon is a charming and gifted comedian who, on his first night, chose to be subdued and at times even serious. That said as much about the uncertain future of “Tonight” as it did about its new host. |||||
Student:
Jimmy Fallon took the helm of the Tonight Show last night in a star-studded debut that marked the show's return to New York City after more than 40 years in LA. The newbie's guests included Will Smith and U2—who performed new song "Invisible" on the roof of Rockefeller Center—but big names including Robert De Niro, Joe Namath, Rudolph Giuliani, Lindsay Lohan, Lady Gaga, Mike Tyson, Joan Rivers, Stephen Colbert, and Sarah Jessica Parker also turned up to plunk $100 on Fallon's new desk after Fallon joked about winning a bet from a "buddy who said that I'd never be the host," reports the AP. Fallon—whose opening monologue was packed with Olympics jokes—paid tribute to the show's history and previous hosts, as well as his fans and family, Mediaite notes. So how did he do? With no drastic changes to the show's formula, "he remained funny, gracious, bubbly and, above all, comfortable," decides Frazier Moore at the AP. But Alessandra Stanley at the New York Times notes that with the show's future uncertain in the digital age, Fallon's debut was "steeped in tradition and solemnity" and he "made nice more than he made jokes." He is a "charming and gifted comedian who on his first night chose to be subdued and at times even serious"—a choice that says as much about the show's future as it does its new host, she writes.
