James was on the beach, and could not understand why Bob had attracted all the girls, while he had no luck. So he asked Bob, "Why do you get all the girls and I get nothing?"

Bob replied, "Take a potato and tuck it in your swimming trunks. It drives the women wild!"

So, James stuffed a potato in his suit and paraded up and down the beach. Several hours later, he still had no luck.

James went to see Bob again and said, "I've tried the potato and it doesn't work!"

Bob looked at James and asked, "Have you tried putting the potato in the front?"
