Rob gives 2,000 high fives standing by the escalator during the morning subway commute in NYC.

This is one of over 80 different missions Improv Everywhere has executed over the past seven years in New York City. Others include Frozen Grand Central, the Food Court Musical, and the famous No Pants Subway Ride, to name a few.

Visit their website to see tons of photos and video of all of their work, including behind the scenes information on how this video was made.

I like when people do something like that. Such missions remind all of us that we are the parts of one whole, they erase all the borders between people. We start feeling each other, we become better. Let's be kind to each other!

You can just smile to the person beside you, and even this simple action will make a big difference to the whole world!
