Here’s a video of Beardyman at a supermarket / grocery store, where he starts out as a bored cashier but gets inspired to do some beatboxing along the way.  If only the cashiers at Walmart could do this…

He has a number of other videos out, and he performs live, too.  If you care to experience more of his “beatology”, here’s a music video of DOLBYMAN featuring Beardyman performing all the parts, which covers several musical genres.
