When Dwayne Johnson visited The Tonight Show on Wednesday night, host Jimmy Fallon decided to mix it up—and instead of his usual sit-down interview, he and "The Rock" hit up Universal Studios.

The late night TV host opened a new ride called "Race Through New York"—which expands on some of Fallon's most famous bits from his show—before the pair masqueraded around Universal Studios in mascot suits competing for fan interaction.

The undisputed highlight of the video: When a lifelong fan of Johnson's realized who was under the costume, he almost broke down in tears.

Wednesday was a big day for "The Rock," as the highest-paid actor in the world also released his latest line of training gear with Under Armour, which included his very own training sneaker.
