Windows 7: Mind "mess"

Made this thread because I figure there are lots of intelligent people here, and lots of people who surf the internet a lot, etc...who can give me examples of some good "mind-ucking" quotes. So, the "rules" are : if you have taken the quote from a person or movie, books and such, please write the quote, and where it's from. If you wrote it yourself, just say so. They don't have to be truly mind blowing, but I'd rather quotes that make you think and go "WOW" rather than quotes about life, love, death, etc.
I'll start it off with a few:

"The next statement is true. The previous statement is false" - Not sure if it's from a specific thing, but I found it while learning the term "paradox".

"I am nobody. Nobody is perfect. Only God is perfect. Nobody is God. God is nobody. I am God" - Saw this one commented in a youtube video about Charles Manson, not sure if it was C.M who said it, but I believe it's clearly a variation of "I am nobody, nobody is perfect, I am perfect"

Hope to get some good results, I love these kinds of sayings/quotes!
