A father buys a lie detector robot that slaps people when they lie…
He decides to test it out at dinner one night. The father asked the son what he had done that afternoon. The son says: “I did some schoolwork.” The robot duly slaps the son… “OK, OK I was at my friend’s house watching movies!” The son replies.
“What movie did you watch?” Asked the father.
“Toy Story" the son replies - again the robot duly slaps the son.
“OK, OK!” The son says: ‘we were watching some porn!”
The father replies: “What? At your age I didn't even know what porn was!” - to which the robot duly slaps the father!
The mother laughs and says: “Well - he certainly is your son!”
The robot then duly slapped the mother!!
