Man walks into a bar with a live full grown alligator.

The bartender says, "Buddy, you can't bring that thing in here. It'll bite someone and I'll get sued."
 
Man says, "No, it won't. It's tame. I'll prove it to y'all."

He opens the gator's mouth, takes his cock out, and holds it between the gator's mouth for five minutes.

"See I told y'all. Anyone else care to try?"

After a bit of silence, a drunk at the end raises his hand.

"Sure, I'll try. But I don't think I can hold my mouth open that long!
