A simple answer. Also: an question that contains it's own answer.
Comes from the board game Trivial Pursuit. One version had these questions (paraphrased):
What do you get when you cross a kumquat and a lime?
What two fruits does a limequat come from?
Family friend: OK this question is to win the game..."What famous baseball player shares his name with a candy bar?"
Rest of family: "LIMEQUAT!!!!!!!!! Pick another question!!!"
