A guy walks into a bar with a crocodile under his arm, puts the crock on the bar and says, "I'll give anyone $1000 if he'll do this, otherwise, you buy all my drinks the whole night." Everyone agrees, so he hits the croc over the head with a beer bottle, and when the crock opens it's mouth, he puts his manhood between its jaws.
After a minute, he takes his manhod out of the crock's mouth and hits the croc in the head again with the beer bottle. Looking around the bar he asks if anybody wants to give it a go.
After a long pause, a young girl in the back says, "Yes, sir, I'm willing to give it a try, but you have to promise me you won't hit me in the head with a beer bottle..."
