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
of his good time being spoiled by not going. So, he took his costume
and away he went.

The wife, after sleeping soundly for one hour, awakened without pain and,
since it was still early, she decided to go to the party. Since her husband
did not know what her costume was, she thought she would have some fun
by watching her husband to see how he acted when she was not with him.

She joined the party and soon spotted her husband cavorting around on the
dance floor, dancing with every nice chick he could and copping a little
feel here and a little kiss there. His wife sidled up to him and, being a
rather seductive lady herself, he left his partner high and dry and devoted
his time to the new stuff that had just arrived. She let him go as far as
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 had sex. Just before unmasking at midnight, she slipped away
and went home and put the costume away and got into bed, wondering
what kind of explanation he would make for his behavior.

She was sitting up reading when he came in and asked him what kind
of time he had.

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, "I'll tell you, I never even danced 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, you're not gonna believe what happened to the guy I loaned my
costume to."
