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"
