John Stamos 'Cried A Lot' On Son Billy's First Day Of Pre-K: 'He Was Cool'

John Stamos' son Billy recently hit a big milestone: pre-K! "He started a new school, pre-K, and he was cool. I cried – a lot. I drop him off in the car, and I'm all nervous, and I feel bad, and he kind of went, 'Bye, Dad!'" the "Big Shot" actor told Access Hollywood at the 2022 D23 Expo. "I think, in the distance, he might've flipped me off, I'm not sure," he jokingly added. John also teased that "Big Shot" gets "deeper and more emotional" in its second season, which drops on Disney+ on Oct. 12.
