George: What is Tungsten? Or Wolfram.
Alex Trebek: [on TV] We were looking for 'What is Tungsten? Or Wolfram.'.
Jerry: Is this a repeat?
George: No, no, no. Just lately, I've been thinking a lot clearer. Like this afternoon... "What is chicken Kiev?" ... I really enjoyed watching a documentary with Louise.
Jerry: Louise! That's what's doing it. You're no longer preoccupied with sex, so your mind is able to focus.
George: You think?
Jerry: Yeah. I mean, let's say this is your brain. [holds lettuce head] Okay, from what I know about you, your brain consists of two parts: the intellect, represented here [plucks tiny piece], and the part obsessed with sex. Now granted, you have extracted an astonishing amount from this little scrap. But with no-sex-Louise, this previously useless lump, is now functioning for the first time in its existence. [eats the tiny piece]
George: Oh my God. I just remembered where I left my retainer in second grade. I'll see you later.
