Fair Dinkum Mate

 A tourist arrived in Australia, hired a car and set off for the outback.
On his way he saw a bloke having sex with a sheep. Deeply horrified, he pulled up at the nearest pub and ordered a straight Scotch. Just as he was about to throw it back, he saw a bloke with one leg masturbating furiously at the bar.
"For fuck's sake!" the bloke cried, "what the hell's going on here? I've been here one hour and I've seen a bloke shagging a sheep, and now some bloke's wanking himself off in the bar!"
"Fair dinkum, mate," the bartender told him, "You can't expect a man with one leg to catch a sheep"
