Doug Hennings! He was one of the first impressions I ever did as a kid. I don't remember the specifics, just that it included a drawn-out hippy voice and also a lot of references to "illusions," "reality," and, "the world of magic!" Oh wait, maybe that was pretty much the whole thing: "ILLUSIONS become REALITY in the world of MAGIC!!!" I also did a pretty good Kwicky Koala.

Oh, and Monkey Too: fuck your thread. You've got clay feet.
