I went to high school with identical twins. I always thought about the jokes you could pull off. Dress alike and fool the neighbors. Switch classes and have the teachers not even know! I'm sure the twins I knew back then tried a couple of those scenarios, but I don't think they ever tried anything this ambitious. An improv group comprised of 4 sets of identical twins tried to convince a subway full of people that time travel is possible! How freaked out would you be if you witnessed this?
