A father bought a lie detecting robot that slaps people when they lie.
He decided to test it out at dinner one night.
The father asked his son what he did that afternoon. The son said, "I did some
homework."
The robot slapped the son.
The son said, "Ok, Ok. I was at a friend's house watching movies."
Dad asked, "What film did you watch?" Son said, "Toy Story."
The robot slapped the son again.
Son said, "Ok, Ok, we were watching porn."
Dad said, "What? At your age I didn't even know what porn was."
The robot slapped the father.
Mother laughed and said," Well, he certainly is your son."
The robot slapped the mother.
