How about giving 2,000 ‘high fives’ on your way to work?

A group of Pranksters gave out 2,000 high fives by standing next to a subway escalator during the morning rush. Five additional pranksters spread out along the adjacent stairs, holding signs that prepared commuters for the upcoming high five fun.

People on the further escalator watch the high fives

Rob executed a few “double high fives” when people passed up the steps

They lasted 45 minutes, staying through the bulk of the morning rush. On overage Rob passed 2,700 people and calculated that around 75% of commuters played along.
