Denise

Dennis is your golfing buddy that lost a bet to you. He must dress as a woman and play a round of golf with you as his payback for losing the bet. He shows up for the round looking better than expected so you spend the day calling him Denise and telling the other golfers that he is your “girlfriend* to further antagonize him. While playing on the back nine, an errant golf shot hits him on the head, knocking him unconscious. When he awakes, he’s lost his memory but seems convinced his name is Denise and he really is your girlfriend.
