A man walks into a bar with his pet alligator and orders a beer. The barman says "Get that thing out of here! I don't need any deadly animals in my bar!"
The man says "Hey, this 'gator is as tame as they come! Watch, I'll show you..."

The owner then proceeds to whip out his dick and place it in the 'gator's mouth amongst the massive rows of teeth. To prove his point further, he takes a stick and begins hammering the 'gator over the head with it.

The owner removes his cock from the 'gator's mouth without a scratch on it and says "See, this gator wouldn't hurt a fly! Anyone else here care to try?"

An old woman at the back of the bar says "Sure, I'll try it, but only if you promise not hit me over the head with the stick."
