A father buys a lie detector robot that slaps you when you lie.
He decides to test it out on his son at supper. "Where were you last night" "I was at the library." Robot slaps son.
"OK I was at a friends house." "Doing what?" asked the father. "Watching a movie. Toy story." Robot slaps son.
"OK it was porn!" cried the son. Father yells "What? When I was your age I didn't know what porn was." Robot slaps the father.
The mother laughs and says "he certainly is your son!" Robot slaps the mother.
