Cool joke..
 

A man buys a lie detector robot that slaps people who lie. He decides to test it at dinner.

Dad: Son, where were you today during school hours?

Son: At school.

The robot slaps the son.

Son: Ok! I watched a DVD at my mates.

Dad: Which one?

Son: Kung Fu Panda

The robot slaps the son again.

Son: Ok! It was a Porno.

Dad: WHAT? When I was your age I didn’t even know what porn was!

The robot slaps the Dad.

Mom: Hahahahaha! After all he’s your son.

The robot slaps the mom.

That was pretty good.
