Scene: R enters room and sits on bed (as is his wont, and that of just about everyone else as well) and watches me playing Puzzle Bobble.

R: Damn you're fast.
Me: Yup.
R: Is that because women have reactions 10 times faster than men or is it just because you're cool shit?
Me: It's because I've had way too much practice at this.
R: Ah.
Me: Is that true, about the reactions?
R: Something like that. They're definitely faster.
Me: So why aren't women fighter pilots?
R: They don't have big enough dicks.
