The Pickle

There was a guy on the beach with about 25 gorgeous chicks swarming all around him.
Seeing this, a second guy strolls on up to him and asks, "What's your secret?"
The guy whispers, "All you gotta do is stick a pickle in your pants."
In a fluorish, the second guy runs off and stuffs a pickle in his pants. But when he returns to the shore, he soon discovers that every single girl that looks his way, runs off screaming in bloody terror. Confused, he hurries over to the first guyand desperately asks, "Why are all the girls running away from me?"
The first guy looks up and replies, "The pickle's on the wrong side."
