I understood it as a joke. Like a "fart joke", right? Or a "poop joke", or some other "mature" type humor.

You are right Stryker (what up with that anyway?), I am not mature enough to be here, so I will crawl back into my crib, curl into the fetal position, and cry until I fall asleep. All the while "pooping" my pants.
Tee-hee, I said "poop".
