Twi-laff zone: Nigel's crocodile trick

Nigel king of the outdoors walks into a bar with his pet crocodile by his side.
He puts the crocodile up on the bar.
He then turns to the astonished patrons and says: "I'll make you a deal. I'll open this crocodile's mouth and place my genitalia inside.
Then the crocodile will close his mouth for one minute.
Then he'll open his mouth and I'll remove my genitalia unscathed.
In return for witnessing this spectacle, each of you will buy me a drink."
The crowd murmured their unanimous approval.
Nigel stood up on the bar, dropped his trousers, and placed his genitalia in the crocodile's open mouth.
The crocodile closed his mouth as the crowd gasped.
After a minute, Nigel grabbed a beer bottle and smacked the crocodile hard on the top of its head. The crocodile opened it's mouth and Nigel removed his genitals unscathed as promised.
The crowd cheered and Nigel's free drinks were delivered.
Soon enough, Nigel had finished all his drinks.
Nigel stood up again and made another offer. "I'll pay anyone a 100 quid who's willing to give it a try." A hush fell over the crowd.
After a while, a hand went up in the back of the bar.

A Muppet (from a small town) timidly spoke up... "I'll try it! Just don't hit me so hard with the beer bottle."
