After two weeks on a desert island with only each other for company, Bob and George are getting horny.
"Look," says Bob, "Neither of us are gay, but if you pretend to be a women for me, when I'm done, I'll pretend to be a woman for you."
George reluctantly agrees and suffers 10 minutes of painful humiliation as Bob f*cks him up. When it's over, George asks Bob for his go.
"F*ck off," Bob replies, "I've got a headache."
