Potatoe

A man goes to the beach to try and pick up girls. He's there all day without any luck, but see's an old friend just surrounded by beautiful women. In a quiet moment he goes over and asks his friend what he does to attract the women. His friend looks around to make sure no one hears, and says 'Just go to the store and buy a potato. Put it in your swim trunks, and the girls just go wild.' Well, the next day the he tries that, but its even worse than before. If anything, the women are avoiding him. He goes back to his friend, and says 'I did just as you said, but the potato doesn't seem to be helping!' The friend looks at him and says 'The potato goes in front!'"
