Mom: Crash, are you wearing underwear?
Mom: Go put some on.
Crash: I don't wear underwear.
Mom: Remember, we went to the store and you found the perfect underwear?
Crash: I only wear underwear every other day.
Mom: Well, Crash, you didn't wear underwear yesterday, so todays' the day.
Crash: I wore underwear the day before. I only do it in a pattern. Underwear, no underwear, underwear, no underwear.
Mom: Exactly. No underwear yesterday, underwear today.
Crash: Oh. I still won't wear underwear.
