A Man buys a Lie detector robot that slaps people who lies.
He decided to test it at dinner:
Dad: Son where were you today during school hours?
Son: At school (robot slaps son)
Son: Okay I went to the movies!
Dad: Which one?
Son: Harry Potter (robot slaps again!)
Son: Okay I was watching porn.
Dad: What? When I was your age I didn’t even know what porn was!
(robot slaps dad)
Mom: hahaha! after all he is your Son!
(robot slaps Mom)
