Calvert DeForest, a.k.a. Larry "Bud" Melman on Late Night With David Letterman from 1982 to 1993, died last Monday at the age of 85. I have fond memories of watching Late Night anniversary specials, which were often broadcast in prime time (I wasn't allowed to stay up till 12:30 to see Late Night "live," but sometimes my brother and I would tape the show and watch it the next day), and seeing DeForest's various appearances on the show. I never got the feeling he wasn't in on the joke.
Below is a clip from November 16, 1983, of DeForest handing out hot towels to passengers arriving at the Port Authority bus depot in New York City. The man knew how to wield a microphone.
"Welcome to New York, sometimes called Fun City. HAHAHA!!!!"
