According to Brenner's, IMDb page, he was a staple on Johnny Carson's late-night show, making more appearances than any other guest.
Before getting into comedy, Brenner helped write, produce and direct 115 TV documentaries, earning him nearly 30 awards. The comedian also authored several books, most recently, "I Think There's a Terrorist in My Soup," in 2003.
Although he has passed, Brenner's humor will live on. His gravesite will reportedly read: "If this is supposed to be a joke, then I don't get it!" That, again, is according to Abraham.
Twitter was lighting up with messages from other comedians, celebrities, friends and fans. On Saturday, Louie Anderson was among those tweeting. Anderson's sentiments, "RIP to the late great David Brenner, great person, friend, mentor & mensch Love you @KingLaughGetter."
Brenner is survived by his wife, Ruth, three sons and a grandson.
