In this Improv Everywhere prank, people riding the subway run into their future selves, who have come in a time machine to give them a dire warning. Cool, right? Except, in reality, the whole thing is just a bunch of twins. F*cking twins—ya can't trust 'em. "We staged the scene five times total, all on the N train [in New York City]," wrote Charlie Todd, the founder of Improv Everywhere, in a blog post. "We took a break in between each staging so the crowd on the car would turn over."
"Unlike other subway pranks that might get an entire car involved, this one was hyper-focused on the people who happened to be sitting and standing around our playing space. In most performances, it felt like a surprise for just ten people," Todd continued. "I love creating something so ridiculously elaborate (four pairs of twins, perfectly timed staggered entrances on the train) for the benefit of so few people.
Never trust what anyone says on a subway car. And especially never trust a twin.
