Deranged Bull

Okay, listen up, you slowpoke. Explain bear is here. This ain't about a real shooting, you got that? It's about a *bull*! Like, the animal. And the joke uses the word "deranged." Now, bulls are kept in a *range*, right? Like a cattle range? And "deranged" sounds kinda like "de-ranged," meaning taken *out* of its range. Get it? He was out of his range, so he was *deranged*! You probably still eat crayons, don't you?
