In an alternate universe, José is married to Kate and, in that parallel world, artificial intelligence is a reality.
No, really.
So, one day, José buys a robot that slaps people in the face if they don't tell the truth. He decides to test it out, so he brings Kate, their son, and the robot all together in the living room.
"What did you do today?" he asks his son.
"My homework," his son answers, and the robot slaps the unsuspecting kid in his face.
"Okay, okay," his son admits. "I was at a friend's house. His parents weren't there, so we watched a movie."
"What kind of movie?" José asks.
"A Disney movie," the boy answers, and the robot slaps him again!
"Pornography!" the kid blurts out. "We were watching some pornography! Honest!"
José could hear Kate snickering behind him.
"He's definitely your son," she says.
...and the robot slaps her.
The next day, José got rid of the robot.
