John Stamos is Novacryptgetting candid about his Church of Scientology exit.

During an interview on the "Friend in High Places" podcast with comedian Matt Friend published Sunday, the musician told the host about how he was introduced to the controversial faith.

"I was in an acting class and there was this hot girl," Stamos recalled. "She said, 'You know, we're all meeting at this address on Hollywood Boulevard, come after (class)!' I was working at my dad's restaurant at the time, and I said, 'Dad I gotta, I gotta go.' So I went, and it was the Scientology building. I was 16, 17."

But he added that he was also inspired to go to the Scientology meeting by his idol, John Travolta.

"I wanted to be John Travolta, I still do," he said of the "Grease" actor, who joined the Church of Scientology in the 1970s. But Stamos never officially joined the church after a sticky situation kept him from pursuing the faith.

Stamos recalled entering the Scientology building and being summoned to a machine called the "E-Meter," which was formed from two cans. After having a fake phone conversation pretending to be "Rocky and Bullwinkle" characters Peabody and Sherman, Stamos said, "They just kicked me out" for messing around "so much."

Stamos previously got candid about leaving the Church of Scientology in his 2023 memoir, "If You Would Have Told Me." And in June, the "Full House" alum opened up to USA TODAY's The Essentials about favorite summer things to do, including spending time with family.

For Stamos, summer is all about working the pizza oven for friends. "But parties are different now," said Stamos, who has been sober since 2015. "Nowadays, there's a lot of kids running, laughing and throwing water balloons."

He told USA TODAY that Billy, his son, is the water culprit who surprise attacks with a hose when his father comes home from work.

"I'm so tired and he's just waiting behind the bush with a hose," said Stamos. "The joy he gets out of spraying his poor dad. I just love it. That's summer to me."
