I thought this piece/demonstration was very interesting, it is very weird no doubt about it but is still impressive in a sense. For one I dont know how either of them were able to keep their composure the whole time. I would probably start laughing right off the bat. I also like how the two come closer together and begin screaming louder and no longer in sync with each other. For some reason I think its funny more than anything else but that may just be because its so weird to me, but overall I like it.
