To celebrate their 50th anniversary, a husband booked a round of golf
for his wife and himself on a trip to famous old St. Andrews' Golf
Course in Scotland.
On the third tee, the husband hesitated in teeing off and turned
slowly to his wife and said contritely, "Darling, I have to confess
something. Twenty years ago I had a brief affair. It meant nothing. I
hope you can forgive me."
His wife was hurt but said, "Dearest, those days are long gone. What
we have now is far more valuable. I forgive you."
They embraced and kissed.
On the seventeenth tee, the husband was starting his back swing when
the wife blurted out, "I'm sorry, darling, I've been so
conscience-stricken since you told me, but since we're being honest
with each other, I have something to tell you also. Fifty-two years
ago I had a sex change operation; I was a man before I met you. I hope
you can forgive me.
The husband, froze at the top of his back swing, then threw a fit! He
slammed the driver into the ground, kicked the ball into the woods,
stormed off the tee, pushed the golf cart over on its side, broke the
rest of his clubs one by one, then started on his wife's clubs.
He screamed and ranted, "You liar...you cheat ... you despicable
deceiver! How could you? I trusted you with all my heart and
soul...and all these years you've been playing off the ladies' tees?!"
