A man bought a robot that slaps people when they lie, and he decided to try it out at dinner.
“Johnny, where do you go during school hours?” the man asked his son.
“To school,” said Johnny.
The robot slapped Johnny.
“Fine. I go to my friend’s house to watch a DVD.”
“What kind of DVD?”
“A superhero movie.”
The robot slapped Johnny.
“Okay, okay, it was an erotic movie!”
“What?” the man was horrified. “You’re 13 years old. When I was your age, I didn’t even know what an erotic movie was!”
The robot slapped the man.
The man’s wife started giggling. “Well, he is your son so I guess he must take after you!”
The robot slapped the woman.
