The Potato

Frenchie finds himself on vacation in Florida. He goes to the beach to cruise some cute American girls. Having no luck, he sees this blond Apollo type American lifeguard surrounded by Baywatch beauties. Hey you Monsieur the Americain! says Frenchie, how to you get all zee beautiful ladies like that? The American lifeguard replies, listen Frenchie, our girls like to see a big bulge in our bathing suit. Try putting a big potato in your swim trunks, and you'll see what I mean.
10 minutes later Frenchie comes back to the lifeguard, his face now a bright red. You American, you lied to me. I put zee big potato in my trunk, but all zee ladies, they all slapped my face hard. The lifeguard smiling replies...Oh Frenchie! the potato, it goes in the front..NOT IN THE BACK!
