Little Johnny is visiting his cousin in the country and they decide to go for a walk down the back roads. After about three miles they find a used rubber lying by the road.
"Hey," Little Johnny, the dumbass city boys says, "look, some cow lost one of its titties!"
"Let's go give it to the farmer!" says his cousin.
So, they work they way up to the farmhouse. They knock on the door and out comes the farmer.
"Hey, Mister, we found a cow titty. Ya want it back?" says Little Johnny. The farmer didn't feel like conducting a mini sex ed seminar, said, "Sure, uhhh, here's a dollar for your trouble." Little Johnny hands over the rubber and head on back down the road.
After a little while Little Johnny says "You know, I bet we could have got more than a buck if I hadn't drank the milk out of it!"
