One morning a woman was walking out of her front door, when she notices a strange little man at the bottom of her garden. "You're a goblin," she says, "I caught you and you owe me three wishes!".
So the goblin replies "OK, you caught me fair and square, what's your first wish?".
The woman stops and thinks for a second, "I want a huge mansion to live in.", goblins replies "OK, you've got it.". Woman again thinks it over, "My second wish is a Mercedes." "OK, you've got that too."
"My last wish is a million dollars!".
The goblin then says "OK, you've got it. But to make your wishes come true you have to enjoy all night with me."
"OK then, if that's what it takes..."
Next morning the little man wakes the woman up. "Tell me," says the man, "how old are you?"
"I'm 27", she replies
"Oh god", says the man, "27 and you still believe in goblins"
