Mike was a salesman's delight when it came to any kind of unusual gimmick. One day Mike came home with another one of his unusual purchases. It was a robot lie detector.
About 5:30 that afternoon their 11 year old son returned home from school over 2 hours late.
"Where have you been"? asked Mike.
"Several of us went to the library to work on an extra credit project," said Timmy.
The robot then walked around the table and slapped Timmy, knocking him completely out of his chair.
"Son," said Mike, "this robot is a lie detector, now tell us where you really were after school."
"We went to Billy's house and watched a movie." said Timmy.
"What did you watch?" asked Timmy's mother Mary.
"The Ten Commandments." answered Timmy.
The robot went around to Timmy and once again slapped him, knocking him off his chair once more.
With his lip quivering, Timmy got up, sat down and said, "I am sorry I lied. we really watched a pornographic dvd movie."
"I am ashamed of you son," said Mike. "When I was your age, I never lied to my parents."
The robot then walked around to Mike and delivered a whack that nearly knocked him out of his chair.
Mary doubled over in laughter and said, "Boy, did you ever ask for that one! After all, he is your son!"
With that the robot whacked Mary and knocked her off her chair
