I've always greatly enjoyed the way that South Park experiments with its own reality. That is, they use live action stills, live action videos, etc. This is great. In this episode (much like the original Mr. Hankey episode), there is a live action advertisement for the Cherokee Hair Tampons.
This episode is obviously a comment on natural medicine and how bogus it is. People believe that sicknesses can be easily cured and prevented by simple and natural methods, and that the Native people are the people to talk to about it. It's a bunch of crap, just like a Cherokee Hair Tampon.
Great guest appearances.
