A scrawny teenage boy asks his muscular friend how he gets so many girls to sleep with him.
The muscular friend says, “Here’s what you do: next time there’s a party, get a large potato and stick it down your pants and act normal. You’ll see – that’ll turn you into a chick magnet.”
A minute later, all the girls at the party run away from the scrawny kid, screaming and laughing and pointing.
The muscular friend sees this and comes over to his scrawny friend. “Dude,” he says. “You have to put the potato in the front.”
