This is actually a play, and one of the best I've ever seen. I saw Lily Tomlin perform it solo, with about three props -- all of them nondescript chairs.

That quote is said by the character Trudy, a homeless person whose past electroshock therapy allows her to "channel-switch" into other people's brains. It's rather hard to describe the performance, except to say that the quote stand/alone/bitch posted is pretty representitive.

All I have to say is go, go now, experience it and let it change you brain. If Lily Tomlin's stopped performing it in the decade-plus since I've seen it, I understand there's a video of her performing it available.... and in any case, there's a book. Your favorite web search site should bring up dozens of links.
