She was born Caryn Elaine Johnson, but has become a household name as Whoopi Goldberg.
And on Tuesday night’s edition of Watch What Happens Live, Whoopi was asked by a caller, "How and when did you get the nickname Whoopi?"
"I'm a farter," Whoopi said nonchalantly. "You know, when you work in the theater sometimes, you do quick changes and you're running around and, sometimes you're just letting go.
"And it became, that was the joke: Whoopi." (As in the classic Whoopee Cushion.)
The caller also asked while Whoopi's real name was; while she did not give the full answer, Whoopi, 57, indicated that Goldberg was a "family name."
