A man walks into a bar holding a very thick chain. As he gets closer to the bar counter the chain follows him until the door opens again and a large crocodile pushes its way through the door. All the patrons jump up onto tables and generally panic or try to find somewhere safe. The barman pops his head up from behind the counter and shouts out "Are you crazy fella! You can't bring that thing in here!" The man replies "Don't worry he is very well trained." The barman says "I don't think it's possible to train a reptile.

Prove it." The man proceeds towards the pool table and calls the crocodile and makes a gesture with his hand. The crocodile puts its front legs up on the table and opens its jaws wide. The man proceeds to take out his p***s and places it in the corner of the crocodile's jaws. He then grabs a pool cue off the table and bringing it up over his head he swings it down hard to hit the crocodile on the snout. The crocodile closes its eyes and makes a hissing sound but the jaws remain open. The man then turns around and asks "Would anyone else like to try?". A grizzled old woman puts her head up from behind a table and declares "I'll give it a try...but don't hit me so hard with the pool cue!"
