Beating Up an Orphan

Okay, listen up, buttercup. The joke is about an orphan, see? Orphans don't have parents. So, if you rough 'em up a little (which you shouldn't do, by the way, because violence is bad, and you probably can't even do a pushup), they can't run and tell mommy and daddy. Get it? It's funny because it's awful. You're probably the kind of person who still uses training wheels.
