" They did n’t wish that . "

You think you know everything aboutJohn Stamos, but youreallyhave no idea.

Case in point: Did you know that the formerFull Housestar and sometime Beach Boys member was oncerejectedfrom Scientology — the religion that more or less exists specifically todraw infamous people and Hollywood types?

Now, Scientology is a notoriously…interesting group, which classifies itself as a religion. Again, they are the type of organization that’s typically looking toexpandtheir ranks. So what could John have done to be effectively kicked out?

During a recent interview on theFriend in High Placespodcast, John revealed all about his brush with Scientology, and what ultimately earned him the almighty boot.

John says he first came into contact with Scientology after meeting a “hot girl” in an acting class when he was “16 or 17” years old. “She said, ‘You know, we’re all meeting at this address on Hollywood Boulevard, come after,'” he recalled. “I was working at my dad’s restaurant at the time and I said, ‘Dad, I gotta, I gotta go.'”

John described how, while attending a meeting, he was asked to take an e-meter reading. Scientologists claim to measureemotionswith the e-meter device, which is specific to the religious group and not typically used outside of it.

“You’re holding these two cans, so I started, you know, ‘Hello… Peabody in the Wayback Machine!'” he said, explaining that he was making a reference to the classic cartoonThe Adventures of Rocky and Bullwinkleas a joke while doing the reading.

“They didn’t like that,” he said. “I was just fucking around so much that they said, ‘Get out. Get. Go.’ They just kinda kicked me out.”

Wanna know more? Well, according toEntertainment Weekly, John further detailed his brush with Scientology in his memoirIf You Would Have Told Me, which saw release last year.

In the book, John described Los Angeles’ Scientology Center as “grand, ornate, and creepy as fuck — a cross between Chateau Marmont,Disney’sHaunted Mansion, and a mental hospital.”

“She takes me into a weird little office where a weird little man shows me a weird little machine that has a bunch of knobs, levers, and gauges to measure my weird little soul,” he recalled about the woman in the acting class leading him to his e-meter reading.

He also said that, during the reading, he was asked questions about “committing crimes,” “negative thoughts about Scientology,” and “strange sex inquiries” before being “whisked out of the room.”

Yikes! Sounds like a close call… You can watch John’s entire podcast appearancehere.
