The son says "at school dad." Robot slaps the son.
"Ok, I watched a dvd at my friends house!"
"What dvd?"
"Toy story."
Robot slaps the son again. "Ok, it was a porno" cries the son. "What? When I was your age I didn't know what porno was, says the dad. Robot slaps the dad.
Mom laughs. "Hahaha! He's certainly your son."
