“My son did not make his bed. He had his nanny make the bed, which was not allowed,” said theTerminatorstar. “So I came in one time and the bed was made so immaculately that I looked at it and I said, ‘Patrick, did you do that?’ And he said, ‘No, I didn’t.' So I grabbed the mattress, opened up the doors, and threw it off the balcony down into the swimming pool!”
“It gives an example. So he had to, kind of, drag it up, the mattress and the pillows — I threw everything out there,” he added.
