A guy enters a yacht club bar carrying an alligator. Says to the patrons,
"Here's a deal. I'll open this alligator's mouth and place my genitals
inside. The gator will close his mouth for one minute, then open it, and
I'll remove my unit unscathed. If it works, everyone buys me drinks." The
crowd agrees. The guy drops his pants and puts his privates in the gator's
mouth. Gator closes mouth. After a minute, the guy grabs a beer bottle and
bangs the gator on the top of its head. The gator opens wide, and he removes
his genitals unscathed. Everyone buys him drinks. Then he says: "I'll pay
anyone $100 who's willing to give it a try." After a while, Harry Krause
raises his hand. "I'll give it a try," he says, "but you have to promise
not to hit me on the head with the beer bottle."
