"Lazy Sunday" aired on December 17, 2005, when the comedy troupe were little known to even "Saturday Night Live"s most devout fans. By the following morning, it had spread online nationwide. Schaffer and Taccone also were contacted by friends who heard the track played on radio stations and in bars. "Lazy Sunday" inspired a line of T-shirts, released during the initial boom of popularity in the weeks after its release. One of the first viral YouTube videos, it increased the trio's recognizability, particularly Samberg's nearly overnight. Their success, according to "New York", "forced NBC into the iPod age"; the short was initially available after its broadcast through the iTunes Music Store, made free for subscribers. Following his stardom on "SNL", Samberg became a celebrity, being covered in tabloid publications. Their profile in "The New York Times" led to a record deal and their own division at the program: "SNL" Digital Shorts, which the group controlled with complete autonomy. In March 2006, the trio produced their second viral hit, "Natalie's Rap". In the sketch, actress Natalie Portman acts as a gangsta rap star, juxtaposing her clean-cut, Harvard-educated image with profane and shocking lyrics. Portman was the host of the program that week, and came to the three having seen "Lazy Sunday".
