Question: Where was Billboard Frolics' creator born? Passage:Cantor appears in caricature form in numerous Looney Tunes cartoons produced for Warner Bros., although he was often voiced by an imitator. Beginning with I Like Mountain Music (1933), other animated Cantor cameos include Shuffle Off to Buffalo (Harman-Ising, 1933) and Billboard Frolics (Friz Freleng, 1935). Eddie Cantor is one of the four "down on their luck" stars (along with Bing Crosby, Al Jolson, and Jack Benny) snubbed by Elmer Fudd in What’s Up, Doc? (Bob McKimson, 1950). In Farm Frolics (Bob Clampett, 1941), a horse, asked by the narrator to "do a canter", promptly launches into a singing, dancing, eye-rolling impression. The Cantor gag that got the most mileage, however, was his oft-repeated wish for a son after five famous daughters. Slap-Happy Pappy (Clampett, 1940) features an "Eddie Cackler" rooster that wants a boy, to little avail. Other references can be found in Baby Bottleneck (Clampett, 1946) and Circus Today (Tex Avery, 1940). In Merrie Melodies, The Coo-Coo Nut Grove Cantor's many daughters are referenced by a group of singing quintuplet girls. In Porky’s Naughty Nephew (Clampett, 1938) a swimming Cantor gleefully adopts a "buoy". An animated Cantor also appears prominently in Walt Disney's "Mother Goose Goes Hollywood" (Wilfred Jackson, 1938) as Little Jack Horner, who sings "Sing a Song of Sixpence".

Question: Who were the original members of the band who sang "God Save the Queen"? Passage:Joss Whedon and Brian K. Vaughan collaborated in breaking down the story, before Vaughan penned the four-part story individually. Vaughan had previously pitched the broad strokes of the story at a dinner with Whedon, Tim Minear and Drew Goddard as a direct-to-DVD Faith movie. There were some presumptions that Vaughan would have difficulty writing the characters' dialogue, given that he wasn't a member of the TV series' writing staff. Despite so, Vaughan proved otherwise. Whedon himself was compelled to tell Vaughan what great lines he had written to Faith specifically. His writing, like the series', featured numerous pop-culture references. The title itself refers to a verse from the song "God Save the Queen" by the Sex Pistols. Other rock song lyrics are mentioned by characters as well: Faith tells Giles she's "the go-to girl for dirty deeds done dirt cheap," whereas Roden paraphrases Pink Floyd's song "Another Brick in the Wall" with the phrase "as a wise man once said, you can't have any pudding if you don't eat your meat." Giles, sporting a jumper with a Yellow Submarine design, refers to "the great bearded wizard of Northampton": a nod to legendary comic book writer and magician Alan Moore. Buffy refers to Lady Genevieve and her accomplices as Faith's 'droogs', a term used in Anthony Burgess' A Clockwork Orange to define friend or associate. Finally, whilst training, Xander makes reference to Snake Plissken, the eye-patch wearing anti-hero of Escape from New York.
