Have you seen carnies? They're a bunch of ruthless, toothless, inbred sons of b*tches that won't think twice about beating the living sh*t out of you or cutting you if you try to rip them off, and they'll never get caught because they'll be disappearing in just a couple days. You can sneak into the movies, because those ushers aren't going to do jackshit. You can sneak into a high school dance, because all you might get is detention. But you try and sneak into a carnival and get caught, and, yes, security is patrolling, your @ss is grass. You'll be lucky if all you lose are a couple of teeth.
My uncle and his family are carnies. Trust me. Getting caught trying to screw over a carny out of even $3 admission or whatever is the LAST thing you ever want to do. There's stupid. Then there's insane stupid. And trying to cheat a carny is insane stupid.
