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 just 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?', they asked.

'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, 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.' answered Tommy.
The Robot went around to Tommy and once  again
slapped him, knocking him off his chair.

With lip quivering,  Tommy 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.'

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

Marsha was bent double laughing, almost in  tears.
'Boy, did you ever ask for that one! And you can't
be too mad with  Tommy. After all, He is your son!'

The Robot immediately walked around to  Marsha, and
slapped her three times
