CINDY: I ate a lot of popcorn when we saw CLASH OF THE TITANS and got constipated, so I just unleashed the Kraken and now I have a bronc-anus...

DAMON: Mike, stop sitting on the trunk latch of your car. Your Bronc-Anus is hanging out. You have a lot of buttsex or something?
MIKE: In prison such decisions aren't always yours to make...
