Potato Trick

Two big, buff, blond guys were on the beach, trying their best to impress the local babes.
The first blond dude said, "I'm not having much luck with the women here, pal.”
The second blond guy said, "Try putting a potato in your swimming trunks. The babes will love that."
 

Three or four hours later, the first blond dude remarked, "Hey man. I tried that potato trick you told me about, and it seems like I'm getting shunned even worse than before."
The second blond dude looked over his bud for a moment and said, "Uh, Dude! Try putting that potato down the FRONT of your trunks."
