Robot lie detector

Tommy was a chronic lier. You could always count on him to lie when in trouble. So his dad showed up one afternoon with a robot. "What is that?" his wife asked. "That's the newest thing. It's a Truth Robot. It can detect the slightest indication that a person is lying."

When Tommy showed up two-hours late for dinner that afternoon, his dad asked, "Where have you been? "Oh, a-a-a. . ," said Tommy, "several of us went over to the library to work on a project for extra credit."

Suddenly the lights on the Robot started blinking and it walked around the table and bopped Tommy on the head. His father explained that this Robot can detect even the slightest untruth.

"Now," said his dad, "where have you been?"

"We went to Bobby's house and watched a movie."

"What did you watch?" asked his mother.

"A-a-a . .The Ten Commandments." answered Tommy.

The Robot lighted up and bopped him on the head, again. Tommy could see he couldn't keep this up so he readily admitted, "We really watched a movie called, 'The Nympho Queen.'"

"I'm ashamed of you," said his dad. "When I was your age, I never lied to my parents."

Suddenly, the Robot lighted up, moved over to where the dad was and bopped him on the head.

The mother commented, "Well, you can't blame him then. After all, he is your son!" To which the Robot lighted up, walked over to the mother and bopped her on the head.
