John was a salesman's delight when it came to any kind of unusual gimmick. His
wife Marsha had long ago given up trying to get him to change. One day John
came home with another one of his unusual purchases. It was a robot that John
claimed was actually a lie detector.

It was about 5:30 that afternoon when Tommy, their 11 year old son, returned
home from school. Tommy was over 2 hours late.
"Where have you been? Why are you over 2 hours late getting home?" asked John.
"Several of us went to the library to work on an extra credit project," said
Tommy.

The robot then walked around the table and slapped Tommy, knocking him
completely out of his chair.

"Son," said John, "this robot is a lie detector, now tell us where you really
were after school."

"We went to Bobby's house and watched a movie." said Tommy.
"What did you watch?" asked Marsha.

"The Ten Commandments." answered Tommy.

The robot went around to Tommy and once again slapped him, knocking him off
his chair once more.

With his lip quivering, Tommy got up, sat down and said, "I am sorry I lied.
We really watched a tape called Sex Queen."

"I am ashamed of you son," said John. "When I was your age, I never lied to my
parents."

The robot then walked around to John and delivered a whack that nearly knocked
him out of his chair.

Marsha doubled over in laughter, almost in tears and said, "Boy, did you ever
ask for that one! You can't be too mad with Tommy. After all, he is your son!"
With that the robot immediately walked around to Marsha and slapped her three
times.
