Jer: No that's not aliens that's my Swamp Gas. I had all you can eat baby back pork ribs from Chillies.
Brian: The aliens are probing my orifices with hot metal objects! The space ship smells like Hell, maybe I've died and gone to Hell.
Jer: Nah your not being probed you just sat on the Can Cheese.
