Maverick was in the South of France, and could not understand why Biff
had attracted all the girls at the beach, while he pulled nothing.

So he asked Biff, "Why do you get all the girls and I get nothing?"

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

So, Mav stuffed a potato in his suit and paraded up and down the beach.
Many hours later, he still had no woman. Mav went to see Biff again and
said, "I've tried it and it doesn't work!"
Biff looked at the Maverick and said, "Have you tried putting the potato
in the front?"
