So this guy plays at a new club. He's paired with a beautiful woman and they are sent out as a twosome. She suggests that they make it interesting, $10 a hole. Needless to say, by the end of the round, he's out $180.
As they're walking back to the club house, he's angry at losing the money and losing to a woman. But soon she says that she feels bad taking his, money, but that she'll be willing to make it up to him "in other ways." The two enter the empty locker room, and, you know.
Suddenly, as she takes down her pants, he sees that shes . . . A MAN! He freaks out, screaming, ranting and raving.
"Don't get so upset," his playing partner says, "you didn't know. It doesn't mean you're gay or anything."
"I don't care about that," the guy screams, "you were playing from the reds!"
(There's a better way to tell this, but I can't remember.)
I heard that joke too, but the version I heard, a man was golfing with his wife for their 40th anniversary. First tee, he confesses that he had an affair briefly near the beginning of the marriage. Around the 16th tee, the wife feels she has to confess something too. She's a man, and she had an operation done about a year before they met. Yadda yadda yadda, "You've been playing from the red tees?!?!?!" and that's the joke as I heard it.
