One evening, several costumed cast members from Disney World got hammered at the British pub in Epcot and attempted an ascent of Space Mountain.
They were ill-prepared and barely-equipped for the harsh terrain, and even with the help of catwalks and stairs they still lost 3 of their party.
Well, actually, they just lost their oversized heads. A fourth: Pooh Bear, threw up in his costume, and Ariel the Mermaid got her tail caught in the coaster track.
By the time they reached the summit, Security had nabbed them all.
Too bad. They were going to attempt the Matterhorn next.
