Finding a body in the trunk will throw anyone for a loop.

The young man in this NSFW video decided he would surprise his father for dear ol' dad's birthday:

Flew out to chicago for my dads birthday, he didn't know I was coming. My mom picked me up and just before we got to the house I hid in the trunk of the car. She asked him if he could grab a few things from the trunk when she got home...

Imagine the horror you'd feel if you opened your trunk and found someone inside of it -- gagged and bound or not. Unless you're in the mob that isn't exactly something you come across too often, so, yeah, the father was rightfully taken aback.

We give the dad a lot of credit for rolling along with the gag after he realized what was going on. He could've been a jerk and decided that instead of being locked in a trunk, his son should be locked in his room where he can't cause any more heart palpitations.
