When one member of a conversation says something they obviously intend to sound brilliant, but which is either completely moronic or totally inappropriate, another member can respond with this line as a way of pointing out said inappropriateness.
Othello: I'm madly in love with Desdemona, but I fear she's being unfaithful.
Iago: You know, I once had a spicy burrito I felt the same way about.
Othello: (stopping, with his mouth hanging open and his eyes blinking) No thanks, I already have a penguin.
