A father buys a lie detector robot that slaps you when you lie. He decides to test it out on his son at supper. Dad says: «Where were you last night?» «I was at the library,» the son replies. The robot hits the son. «Well, I was at a friend’s house,» the son replies. “What were you doing?” asks the dad. «Watching Toy Story,»
the son says. Then again, the robot slaps the son. The son says, «Okay, it was dirty!» «What?» exclaims the father. «At your age, I had no idea what ‘dirty’ was.» The robot slaps the father. «He’s definitely your son,» the mother says with a laugh. The robot slaps the mother.
