Jill: This is so shocking! Your father had an affair that nobody knew about? I can't believe it. It's like something out of a romance novel. Where do you think they had these secret little trysts?
Tim: You know, Jill, I didn't think to ask.
Jill: Oh, my God! Oh, my God! What if Liddy and your father had a love child?!
Tim: Would you stop it!
Jill: You were saying how hot Elizabeth was. What if she's your sister?
Tim: Now I want to vomit!
Jill: What if you had married her instead of me?
Tim: Would you let this go?
Jill: What if you and your half-sister had had children?
Tim: Well, then I would be the best father and uncle to those kids possible.
