There's a saying that there is dubstep for everything, so naturally, I tested this saying by typing in "chair dubstep" : http://m.youtube.com/#/watch?v=Bw-OxoCDSBA yep, it's kind of funny and  usually has to be for something like this, but I wasn't quite convinced so I searched "potato dubstep" and sure enough, they have that too: http://m.youtube.com/watch?v=FODMIeXmMCI yeah I wouldn't suggest listening to all of that one because it's repetitive  and about a potato,  not much you can do there. I do like dubstep's  granted freedom to make a song about  literally anything, even random subjects such as these.
