Those funny pranksters at Improv Everywhere are at it again. This prank features a human mirror on a New York subway.

To do it, they enlisted 15 pairs of identical twins. Each pair sat across from each other on a subway car. They mimicked each other’s every move.

The regular passengers couldn’t believe their eyes. Double takes were plentiful. I bet seeing this brightened their day. I know it will yours.

Improv Everywhere specializes in large-scale public pranks. These pranks can feature hundreds of volunteers. I’ve featured their work in past Videos of the Day. Watch them prank Grand Central Station and a little league game.
