man dirty joke

A man is driving his eighteen wheeler down the road, when he sees a hitch hiker. So 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. So the trucker has this monkey in the back, and he makes it come up with the men, and he smacks the monkey up side his head, and the monkey gives him a blow job. So after that, the trucker says "Hey man, do you want some of that?" And the hitch hiker says "Sure, but just don't smack me so hard."
