A man walks in to a bar and is shocked to see a very large alligator walking across the floor, so he turns to leave.

"Where are you going?" ask the bartended.

"There's an alligator in here, I'm gone!"  he says.

"No, wait.  This is a pet of mine and he's completely tame."

"You can't tame an alligator."

"Wait, I'll show you." and the bartender walks over to the alligator, opens it's mouth, wips out his johnson and puts it in the alligator's amouth.  He stays like that for 5 minutes and then puts everything back where it belongs.

"See. he says.

"That's the most amazing thing I've ever seen." says the man.

"Would you like to give it a try?"

"Sure, but I'm not sure I can keep my mouth open that long!"
