A Cajun walked into a bar with a pet alligator by his side.
He put the alligator up on the bar and turned to the astonished patrons.
"I'll make you a deal. I'll open this alligator's mouth & place my 
genitals inside. Then the 'gator will close his mouth for one minute. Then 
he'll open his mouth and I'll remove my unit unscathed. In return for 
witnessing this spectacle, each of you will buy me a drink."

The crowd murmured their approval. The man stood up on the bar, dropped 
his trousers and underwear, squatted down and placed his entire 'package' in the alligator's 
open mouth. The gator closed his mouth as the crowd gasped.  After a 
minute, the man grabbed a beer bottle and smacked the alligator hard on 
the top of its head.  The gator opened his mouth and the man  removed his 
genitals unscathed as promised.  The crowd cheered and the first of his 
free drinks was delivered.

After that round of drinks the man stood up again and made another offer.

"I'll pay anyone in the room $100. who's willing to give it a try."

 A hush fell over the crowd. After a few minutes of silence, a single hand 
went up. "I'll try it!" yelled a woman from the other end of the 
bar. "...just don't hit me so hard with the damn bottle...".
