There's a man walking through the park. He looks up and sees another man walking towards him with a pine-apple as a head, with eyes, nose and a mouth.
Curious, he strolls over and asks: "Excuse me, why do you have a pine-apple for a head?"
The person replies: "Well, three days ago, I found a genie lamp. The genie emerged and told me he could grant me three wishes."
"What did you wish for?"
"Well, firstly, I wished for an infinite amount of money to be waiting for me at home. It was granted. Then I wished for the a crowd of beautiful women to be waiting for me at home. It was granted."
"...So how does this explain the pine-apple???"
"...Ah. This is where my third wish comes in! I wished for a pine-apple for a head."
