This joke has divided those whom I have told it to into two groups: those who pissed themselves laughing, and those who just said 'what?'. Personally, Ithink that it is the funniest thing I have heard in ages.
A man walks into a pub. Everything is normal, except that he has an orange for a head.
He walks up to the bar and asks the landlord for a pint. As the landlord is pulling the pint, he asks the man "what the hell happened to you?"
"You'll never guess" says the man. "I was walking along the street when I saw a fairy floating above the path. She said that she would grant me three wishes; anything I desired."
"No way! What did you wish for?" said the landlord.
"For my first wish, I asked for an Aston Martin Vanquish. As soon as I said the words, the car appeared and the keys were in my hand."
"Wow, this is incredible! What did you wish for next?"
"Next, I wished for the most beautiful woman in the world to be on hand to make my every sexual fantasy come true for the rest of my life. She immediately appeared, completely naked, lying on the bonnet of my new car."
"I can't believe this! What was your final wish?"
"Isn't it fucking obvious? I wished to have an orange for a head."
