[1] He announced the guests at the top of each show and the one-liner during the Worldwide Pants title card after the credits and regularly acted in comedic sketches.

Kalter (credited as Alan Roberts) also filmed two game show pilots for CBS - The Challengers by Ron Greenberg Productions/Universal Television in April 1974, and The Finish Line by Bob Stewart Productions in October 1975.

Additionally, episodes of Truth announced by Kalter were taped in NBC Studio 6A, where Letterman later originated Late Night.

He was often portrayed alternately as a sexual deviant (often while grinning mischievously), a powerless sap who was beaten to within an inch of his life and left rolling on the ground writhing in pain, or frustrated at having guests for his own interview segment stolen by host David Letterman.

[2] He was an English and Public Speaking teacher at Baldwin High School on Long Island in the late 1960s and was also the voice of the Michelin Man.
