Speaking to his studio audience, Fallon explained that last time he hung out with Hart, the pair went on a rollercoaster. "Since Halloween is round the corner I wanted to try something even scarier, so today we're going to New York's scariest haunted house," he said. "I'm going to be honest, rollercoasters are okay, I can do a little bit, but I do not like being scared."
That proved true as the pair entered the spooky abode and shrieked their way past zombies, vampires and even a chainsaw-wielding demon creature whom they begged to "Stop it!"
Fallon and Hart were clearly pretty shaken by the time they reached the exit. "If you guys watch this and at any point it looks like I'm afraid, I'm an actor and was acting," Hart unconvincingly told the camera. Watch the clip above.
