As he's walking down an old country road he happens to see a farmer having sex with a sheep. Totally shocked, he quickly walks to the nearest pub and orders a double whiskey. Just as he is about to drink it, he notices a man with one leg masturbating at the end of the bar.
“For the love of God!” shouts the visitor, “What is going on here? I have only been in Ireland a few hours and I have watched as one guy screwed a sheep, and if that's not shocking enough I walk in here and some man is jerking off at the bar!”
“What did you expect?,” says the bartender, “A man with one leg isn't fast enough to catch a sheep!”
