A sad, sad day.

Larry "Bud" Melman has died. It's a sad, sad day in the world of late-night TV.

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.

He made dozens of appearances on Letterman's shows from 1982 through 2002, handling a variety of twisted duties: singing a duet with Sonny Bono on "I Got You, Babe"; doing a Mary Tyler Moore impression during a visit to Minneapolis, Minnesota, where her 1970s show was set; handing out hot towels to arrivals at New York's Port Authority Bus Terminal.
