Tom Hanks portrays Walt Disney in the new film "Saving Mr. Banks," which chronicles Disney's struggles to develop and produce the 1964 classic "Mary Poppins." But Hanks learned more that just the history of "Mary Poppins" during filming — the actor managed to escape from Disneyland with a dirty secret or two.

As he told Conan O'Brien on Tuesday's show, Hanks found out exactly why the Skyway gondola ride is no longer in operation at the park.

"Remember sky buckets? You caught them in Tomorrowland, took them to Fantasyland, went right through the heart of the Matterhorn, came out the other side?" Hanks asked the audience. "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. There was other naughty stuff going on, but there were people that tried to — how do we say this — get the deed done. How to enjoy the e-ticket, maybe the g-ticket, maybe the o-ticket. I don’t know."

Unfortunately for those amorous park-goers, Hanks says a team of workers was assigned to monitor the buckets for un-Disney likes activity and to then escort the frisky riders out of the park once they reached their destination.

Hanks also claims the entire ride lasted only four and a half minutes, in case you were wondering.
