This reminds me of a joke:
Two guys are on the beach and one of them has women flocking all over him. So the other one goes up to him and asks "What is your secret to getting all this hot chicks?"
The guy whispers to him "I put a potato in my swim trunks." So the other guy thanks him and goes home.
The next day the guy still has chicks all over him, but the other one has women running away from him, some are even screaming.
Later on the other guy comes up to the first guy and says "I did what you told me, I put the potato in my trunks, but the women are running from me."
He replies "You're supposed to put the potato in the FRONT of your trunks."
