Until now, you didn't know you needed an encouraging fist bump from a random guy on a motorcycle, did you? 

Meet Nathan Bennett, a Grand Rapids area motorcyclist who enjoys sharing a fist bump with random people as he makes his way around the city.

His new hobby began innocently enough according to his YouTube page:

One morning on my way to work I was at a stoplight and I just had the idea to give a person a fist bump and after the first fist bump and the big smile it put on the persons face it made me want to keep doing it. So I kept doing it so I can put together a compilation video and this is how it turned out, the videos were recorded over the course of a month!

Perhaps you've been fist bumped by Nathan while out and about. Well, chances are, you're on this video!
