Videos of people doing impressive things with their mouths always do well on the internet. One of those things is beatboxing. Maybe it's because most of us couldn't do it if our lives depended on it, maybe it's just because it sounds cool, but those videos never get old -- though sometimes they do get a little repetitive.
This McDonald's patron, however, takes it to a new level, not only beatboxing, but mimicking actual dubstep sounds using the straw from his soda cup. And it sounds freaking awesome. So congrats, dude. You've found the literal most impressive thing a person can do in a McDonald's.
