A few days before Jack married Wendy, he had her name tattooed on his penis to show her how much he loved her. When erect, the name was fully visible; when deflated, it read Wy.
After the ceremony, they went to Jamaica on their honeymoon. Wendy was delighted with Jack's "special emblem of devotion." Their hotel had two beaches, one traditional and one nudist.
After two days of the traditional beach, Wendy suggested visiting the clothing-optional beach.
As Wendy lay on her towel in the hot sun, she asked Jack if he'd bring her a cold drink. He walked across the sand to the little hut and asked the bartender, who was also naked, for two pina coladas.
Jack tried not to stare, but he noticed that the bartender also had "Wy" tattooed on his penis. "Hey," Jack said and smiled, "what a coincidence. Your girlfriend must also be named Wendy."
"Oh no, mon," the bartender said and laughed. "Mine say WELCOME TO JAMAICA. ENJOY YOUR STAY."
