''Men and women can't just be friends; the sex part always gets in the way."

Well, well, if it isn't InuYasha? How's that Kagome thing working out?... Ohhh, 200 episodes and you guys haven't even gotten together. HAHAHAHA!

Genis: Okay, Emil, just be straight with me. How do you feel about Marta?
Emil: How do I feel? Well, I guess...
Tenebrae: Don't say it!

Genis: You know, "spiteful" may be the perfect word for Tenebrae.

Penny: Look, Sheldon, sometimes it's more fun for things to be uncertain. I mean, look at Leonard and me. We met, we dated, we broke up, and now we're back together and who knows what's going to happen!"
Sheldon: Oh please. We all know what's going to be happen.
