A bloke walks into a bar with a crocodile. Predictably, most of the patrons scarper and the barman complains. But the owner of the croc says, "No worries, mate, watch this." Picking up a bottle, he smashes it over the croc's head. No reaction, other than a wag of the head. The bloke then gets his cock out and puts it in the croc's mouth, but again the croc just wags its head. Then a fellow punter asks if he can try it.
"Help yourself, mate," says the owner.
The punter proceeds to smash a bottle over the croc's head and then put his cock in its mouth. The croc just gives its usual response. Word spreads and several blokes try it. Then an old biddy walks up for a go.
"Can I just make one request, though?" she asks the owner.
"Ask away, " he replies.
"Don't hit me so hard with the bottle."
