Chap walks into a bar in the African bush with a crocodile on a lead.
He says to the barman "I'd like a beer for myself and a Zulu for the croc. He has a taste for human flesh and I want to keep him happy".
The beer is poured and a (bound hand and foot) magnificent example of Zulu warrior is put before the crocodile - which the croc consumes greedily.
Two beers and two Zulu warriors later the man is asked "anything else, sir?"
"Okay - another beer for myself and another Zulu for the croc".
"No problem" - another beer and another Zulu are brought to them.
Twenty minutes later, the order comes again "a beer for myself and a Zulu for the croc".
"Sorry sir, says the barman, I can do the beer but the croc's had the last of the Zulus. However, out the back we have a tribe of pygmies - as a special deal I'll do you two pygmies for the price of one Zulu. You okay with that?".
"Sorry chum, no. I'll just take the beer. He's a real b*****d when he gets on shorts".
