A man is driving his eighteen wheeler down the road, when he sees a hitch-hiker. The trucker stops and picks up the man.
While they are driving down the road, the trucker says, "Hey man, you wanna see something pretty cool?"
The hitch-hiker says, "Sure."
The trucker reaches behind the seat and pulls out a monkey. He brings it up into the front seat, smacks the monkey up the side of his head, and the monkey gives him a bl*w j*b.
After he's done, the trucker says, "Hey man, do you want some of that?"
The hitch-hiker replies, "Sure, but just don't smack me so hard."
