A guy is stranded on a deserted island with a famous supermodel. Within a week the two lonely castaways are making love. Then, one day, the guy turns to the supermodel and says, ""I was hoping you could do me a favor."" ""Sure,"" she replies. ""First, put on my clothes,"" he says. ""Fine,"" she says while getting dressed. ""Great. Now draw a beard on your face with this coal I found,"" he says. ""OK,"" she replies. ""That's perfect. And would you mind if I called you Joe?"" ""I guess not,"" answers the supermodel. ""Great,"" replies the guy. ""Joe, you're not going to believe who I've been banging!""
