A popular book written by some mathematician guy who went under the psedenym 'Lewis Carol'. This (As well as Carol's other literary work "Through the Looking Glass") was later addapted into a Disney movie that has obtained an avid cult following for being so awesome.
There is a certain amount of drug propaganda supporting this movie/book because of Carol's... imaginative pursuits.
Oh, and the storyline has been adapted into some sort of macabre-type videogame.
"Alice in Wonderland is a trippy book. Ahah! Get it! TRIPPY!"
