Disneyland is known as the happiest place on earth, and according to Tom Hanks, visitors were determined to keep it that way, in a not so PG manner.

Hanks appeared on "Conan O’Brien" Tuesday evening to promote his new film “Saving Mr. Banks” in which he plays Disneyland founder Walt Disney.

The cast and crew spent a lot of time filming in the famed amusement park, so Hanks became privy to some interesting Disneyland trivia.

“You ask questions like, ‘what happened to this ride?’” the actor shared of recreating the original 1960s Disneyland.

“And then they tell you why there are no sky buckets anymore. Remember sky buckets?" Hanks asked O'Brien of the popular gondola lift attraction “Skyway” that closed in 1994.

"You caught them in Tomorrowland, took them to Fantasyland, went right through the heart of the Matterhorn. Came out the other side?”

“One of the problems was, there were a lot of people trying to join, let’s call it, the Mile High Club. In the sky buckets,” Hanks shared.

“There were other naughty stuff going on, but there were people that tried to, how do we say this, get the deed done."

And in case you're curious, the ride lasted “maybe four-and-a-half minutes,” according to Hanks.

But despite the crazy facts one learns while working at the theme park, Hanks loved his time filming in the magical location and likened his experience to being 13 again.

"Oh, I get it,” the actor joked, “I'm 13. I'm dead at 13 and I've come to heaven."
