Bartholomew: Bro, I'm telling you! Something is wrong. My Ballstuition is telling me so!
Galileo: How is Ballstuition telling you so?!
Bartholomew: My testicles are clapping against each other. They're trying to tell me something.
Galileo: What's your Ballstuition telling you?
Bartholomew: They're either trying to say that woman I slept with the other day is either dead or pregnant. I don't know yet.
Galileo: Hopefully it's not the latter of the two.
