An English taxidermist is sweating his way through the Australian outback when he comes across a bar.
He staggers in between the beer swilling locals and, in his well educated voice, asks the bartender, "May I have a gin and tonic, please, my good man."
One of the locals says to his mates, "Geez, cobbers, what kind of a fucking man's drink is that?"
Then, turning to the Englishman, "Hey! You! Yes you, you fucking Pom! Gin and fucking tonic are you some fucking kind of a poofter or something?"
"Ac...actually," the Englishman, terrified, replies, "I'm a taxidermist."
"Oh yeah? And what's a taxidermist, then?"
"I mount d..d..dead animals."
"It's alright, cobbers," says the local, turning to his mates, "he's one of us!"
