I also really like the bug Huelsenbeck introduced to it. The whole, Dada is (paraphrasing) only about our generation, it is for us and us alone.
And then the very next thing he says is how artists are incapable of looking beyond their dialectic, and it's unreasonable to look at the world any other way.
Which completely skews what he just said. It turns itself upside down and speaks inversely. And it's fucking brilliant the way he did that.
