A Kid Keeps Lying To His Father So The Dad Buys A Lie...

Joke: A kid keeps lying to his father so the dad buys a lie detector robot who will slap him if he tells a lie. The next morning the father asks his son where he was the night before. "I was at Joeys house doing my homework" The robot slaps him. His dad says that was a lie and asks what was he really doing. The kid says "we were watching Toy Story" and he gets slapped again. When he asks again what were you really doing, the kid admits they were watching porn. "See when you tell the truth you won't get slapped". The dad then says "when we were kids we didn't even have porn" The robot then slaps the father. The mom laughs and says" well he is you kid after all". So the robot slaps the mom.
