One of late night TV's leading men, Jimmy Fallon, is celebrating his birthday today. The Tonight Show entertainer and Saturday Night Live alum is turning 43, and we're kicking off his big day with 11 of his funniest moments on TV.

The newly minted 43-year-old got us hooked on his impressions and comedy when he first joined the SNL cast in 1998. In 2009 he took over Late Night and subsequently became the face of The Tonight Show in 2014. Fallon and career are unstoppable—and he's got the Emmy Awards to prove it!
