Heartfelt Tribute to David Letterman from Jimmy Fallon

Tomorrow we gear up to say goodbye to David Letterman on the Late Show. Jimmy Fallon took five minutes out of his show last night to offer a very heartfelt tribute toDavid Letterman as the longtime late night host prepares to call it career. Fallon spoke about being a lifelong fan of Letterman and the impact he had on late night television as well as the influence he had on every other host. Letterman's last show will air tomorrow night.

He also showed a very cool yearbook from 8th grade where his teacher predicted that he would replace David Letterman, that didn't happen exactly but she sure was close. He was one of Jimmy's big influences it seems in this industry.
