Or, from the movie Clueless:

Heather: It's just like Hamlet said, "To thine own self be true."
Cher: Hamlet didn't say that.
Heather: I think I remember Hamlet accurately.
Cher: Well, I remember Mel Gibson accurately, and he didn't say that. That Polonius guy did.

haha I couldn't help myself I had to do it.
