Kevin Hart may be brave enough to perform in front of thousands of people, but one thing that he does not have the guts to do is ride a roller coaster.
"I don't like 'em," Hart told Fallon. "You know damn well I don't like no roller coasters."
The show is broadcasting from Universal Orlando theme park in Florida this week, so Fallon, 39, took advantage of the location to help Hart overcome his fears.
The funny man, who was on the talk show to promote his new movie Think Like a Man Too, was convinced by Fallon to ride Universal Studios' Hollywood Rip Ride Rockit coaster.
"My palms were so clammy… I don't like roller coasters, and you made me do it," Hart said.
"Think like a man, we gotta act like a man!" Fallon retorted. "We manned up."
The two men braved the fast-moving roller coaster in a filmed segment, which shows Hart losing it and wailing as he and Fallon whip around curves and drops.
