How rude! Turns out "Full House" back in the day.

Lifetime's "Grandfathered," the actor confessed that it's all true.

"The Olsen twins cried a lot. It was very difficult to get the shot. So that actually is 100 percent accurate," he told reporters. "I said, 'Get those kids ...' [gestures to get rid of them] and they brought in a couple of unattractive red-headed kids. We tried that for a while and that didn't work. I said, 'Alright, get the Olsen twins back.' That's the story."

Funnily enough, Stamos is working with another pair of twin girls, who play his granddaughter on "Grandfathered."

He joked, "I whisper in their ears that I made other twins a lot of money!"
