Mom: (points to end of couch) Lie with your head here.
Ethan: Why does it matter?
Mom: I dont want your feet over there.
Ethan: Man, there’re a lot of rules at this hotel…
Mom: And don’t fart on my couch, either.
Ethan: What could a fart do? It can’t stay in the couch forever.
Mom: It could, if its potent enough. Dad’s done it.
