A new machine came to market, one that slaps those who lie. A father decides this could be of some use, and purchases one to take home.
A little while later, the school principal calls, telling him his son skipped school. Outraged, the father confronts his son, “Son! Where were you during school hours today?”
The son replies, “At school!” to which the machine slapped him. “Ow! Okay I lied I was at the movies.”
Furious, the dad asks, “Which one?”
Mark replies, “Harry Potter.” He’s slapped again and says, “FINE it was a R18 movie.”
Surprised the dad exclaims, “At your age I would have never done something like that!” The machine slaps the dad.
Watching it all unfold, the mother comes in laughing, and chimes in saying, “No surprise there, after all he is your son.” The machine gives her a slap.
