One redditor ran into Jim Carrey while having car trouble, and the actor went above and beyond to help. "Jim Carrey gave me a ride to the gas station after my car ran out of gas in Bel Air. I told him I was a huge fan of Ace Ventura and I could mimic his laugh from the movie," the redditor wrote. "Then we both had our heads out the window cackling away. He bought my gas and drove me back to my car. One of the greatest moments in my life."
