On The Tonight Show Starring Jimmy Fallon Jimmy Fallon and Justin Timberlake found themselves in a sketch playing campers at Camp Winnipesaukee in 1993. Timberlake and Fallon were in their cabin trying to get some shut eye but they just couldn't help but want to sing some of the latest 1990's songs including "What's Up?" by The 4 Non Blondes even though it was lights out. Although they tried singing the song softly to start, they ended up belting out the tune and drawing the attention of camp director, Mr. Fletcher played by Keegan-Michael Key. Key asked the boys to stop their "ruckus" but despite his warnings, as soon as he left they jumped right into more singing.
The second time he came in, Key really laid down the law, getting right in Jimmy's face, letting his whistle dangle in Jimmy's face, which Jimmy took the opportunity to blow.
Throughout the whole sketch, Timberlake could barely keep it together and the whistle moment put him over the edge. "You okay?" said Key. "Yes, it's allergies," said Timberlake.
