Lie Detecting Robot

[mclovin]

A father buys a lie detector robot that slaps you when you lie. He tests it on his son at supper. Father asks his son, "Where were you last night?" Son replies, "I was at the library." Robot slaps son. "Ok I was at a friends house." "Doing what?" asked the father. "Watching a movie." says the son. "What movie?" asks the father. "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.
