You're walking down the sidewalk and you see a guy with his arm in the air. If you're in New York, you'll know he's hailing a cab. This guy thought it'd be funny to run up and give them high fives. How do you think these New Yorkers took to his prank?

As you can tell from the reactions, they seemed very good-natured by it. Just a simple high five to brighten your day.

Don't forget to high five the ones you love.
