Sally Rogers:
Rob, if she were planning a surprise party, she certainly wouldn't let you hear her inviting everybody.

Buddy Sorrell:
Yeah, and she wouldn't have you invitin' Mel.

Rob Petrie:
No, that's just exactly what she WOULD do. You see, what she's doing, in chess, is called the double-reverse half-truth check-your-mate gamble. I'm gonna play right along with her and let her check her mate, that's all.

Sally Rogers:
Well, you may be right, Sebastian, but I think she's employing the old I-planned-to-give-him-a-surprise-party-but-the-rat-found-out-about-it-so-I-changed-my-plans bit.

Buddy Sorrell:
Hey, I don't know which one of you guys is right, but there's a free meal in there some place and I'M GOIN'.
