A husband and wife are playing golf and, just as he's about to tee off on the fourth hole, the husband says:
"Darling, I have to tell you something. Years ago, not long after we were married, I had an affair with another woman. I'm so sorry, but it's been eating at me all these years and I just had to tell you."
"Darling," says the wife, "if it was that long ago and you've never done it again, I forgive you because I love you."
They go on playing and then, just as they get to the 18th hole, the wife says:
"Darling, I need to tell you something too. Years ago, before we were married, I had a sex change, I was born a man."
The husband looks at her and then smashes his putter against his golf bag, ranting and raving.
"You lying, despicable *BITCH*!! You never told me?
"And all these years you've been playing off the *LADIES* tee!!"
