The Red Dot
The one thing I never got about that episode is, why didn't George just lie to Lippman about having sex with the cleaning woman? When Lippman asks him if he did it, he could have just lied and said "No, she's lying never happened".
George lies all the time, so why would he admit it? Of course, it wouldn't have been as funny because then we wouldn't have George's "Was that wrong"? dialogue, but it's something I've always wondered.
