A Bit of Halloween Caution!
A couple was invited to a swanky masked Halloween Party. She got a terrible
headache and told her husband to go to the party alone. He, being a devoted
husband, protested, but she argued and said she was going to take some
aspirin and go to bed, and there was no need for his good time to be spoiled
by not going. So he took his costume and away he went. The wife, after
sleeping soundly for about an hour, awakened without pain; and, as it was
still early, decided to go to the party after all. In as much as her husband
didn't know what costume she'd be wearing, she thought she'd have some fun
by watching her husband to see how he acted when she wasn't around.
She joined the party and soon spotted her husband cavorting around on the
dance floor, dancing with every chick he could, getting a little kiss here
and a warm squeeze there. His wife went up to him and being rather seductive
herself, he left his current partner high and dry and devoted his time to
this new babe who had just arrived.
She let him do whatever he wished, naturally, since he was her husband.
Finally he whispered a little proposition in her ear and she agreed, so off
they went to one of the cars and they did it all! Zowie! Just before
unmasking at midnight, she slipped away and went home, put the costume away
and got into bed, wondering what kind of explanation he would have for his
behavior.
She was sitting up reading when he came in. She asked how the evening had
been? He said "Oh, the same old thing. You know, I never have a good time
when you're not there." Then she asked, "Did you dance much?"
He replied, "You know, I didn't dance even one dance. When I got there, I
met Pete, Bill Brown and some other guys, so we went into the den and played
poker all evening.
But I'll tell you...from what I heard, the guy I loaned my costume to, sure
had a real good time!"
