John was a salesman's delight when it came to any kind of unusual gimmick. His wife Marsha has long ago given up trying to get him to change.
One day, John came home about noon and told Marsha that he had gone to a nearby city and purchased a Robot. It was no ordinary robot, but it was in fact a Lie Detector. He said it had to charge 4 or 5 hours, and then he would show her how it worked.
At 5:30 that afternoon, Ed, their 11 year old son, came in from school, nearly 2 hours and 15 minutes late. Both parents were understandably angry.
'Where have you been? Why are you over 2 hours late getting home?', they asked.
'Several of us went to the library to work on an extra credit project,' said Ed.
The Robot walked around the table and slapped Ed, knocking him completely out of his chair.
'Son, this robot is a lie detector, now tell us where you went after school.'
'We went to Bobby's house and watched a movie.'
'What did you watch?', asked Marsha.
'The Ten Commandments.'
The Robot went around to Ed and once again slapped him, knocking him off his chair.
With lip quivering, Ed got up, sat down and said, 'I am sorry I lied. We really watched a tape called Sex Queen.'
'I'm ashamed of you Son,' said John. 'When I was your age, I never lied to my parents, never tried to see dirty pictures much less dirty movies, told dirty jokes, nor did I misbehave.'
The robot walked around to John and delivered a roundhouse right that not only knocked him out of his chair, but out the back door and half way across the patio.
When he came back inside, Marsha was bent double laughing, almost in tears. 'Boy, did you ever ask for that one! And you can't be too mad with Ed. After all, he is your son!'
The Robot immediately walked around to Marsha, and literally slapped the shit out of her, not once , but three times.
