"My 6-year-old has a Bieber toothbrush!" he told Ann Curry.
But Sandler is really best when he's channeling his own inner 6-year-old -- as he appears to do in "That's My Boy," where he plays a man who never really grew up even though he had a son (Samberg) to raise, and who is now dealing with the consequences.
"We knew that this was a filthy movie right out of the gate, so we went straight filth and enjoyed embracing the dirtiness," he said, advising parents not to bring their young children.
With a per-film average gross of $72.4 million and having grossed over $3 billion since he first started making movies in the 1990s, Sandler could stop acting and writing tomorrow and retire wealthy, but he said he probably wouldn't be happy if he did that.
"What else am I supposed to do with my life?" he asked. "I make movies; I like making movies. When I'm not making them I kind of stare at the wall and say, 'Now what?' I hang out with my kids a lot. I hang out with the wife a lot. We have fun together, but I like to work."
So expect to see more Sandler films in the future. Meanwhile, "That's My Boy" opens June 15.
