Improv Everywhere 'causing scenes of chaos and joy in public places' since 2001.
'Agent' Rob gave 2000 high fives to commuters during rush hour on the New York subway. This simple act had a surprising effect on the usually grumpy and silent morning travellers, it made them smile!
'It was awesome watching the reactions of people before, during, and after the high fives. I’d say around 75% of the riders gave Rob a high five. There were some people who were both listening to music and reading a book who didn’t look up to notice what was going on. A small percentage seemed suspicious of us and elected to keep their hands to themselves. Most people smiled and high fived. Some people kept a straight face during the high five, but then privately smiled to themselves a few moments later. Watching people after they gave a high five was almost more fun. Almost everyone was left with a smile.
