According to CNN.com:
"The balding, bespectacled nebbish who gained cult status as the oddball Larry "Bud" Melman on David Letterman's late-night television shows has died after a long illness.
Brooklyn-born Calvert DeForest, who was 85, died Monday at a hospital on Long Island, the Letterman show announced Wednesday."
I always thought Melman was one of the funniest parts of the Letterman show. Melman's brutal sincerity made a nice complement to Letterman's tongue-in-cheek style. Melman brought a comic sledgehammer to Letterman's straight man setups.
The saddest part of the story:
"There will be no funeral service for DeForest, who left no survivors."
God bless you DeForest. You made a lot of people laugh, and that is a pretty good legacy to leave behind.
