"'Twas brillig, and the slithy toves, did gyre and gimble in the wabe: All mimsy were the borogoves, and the mome raths outgrabe. The Jabberwock, with eyes aflame, jaws that bait and claws that catch. Beware the Jabberwock, my son, the frumious Bandersnatch. He took his vorpal sword in hand, the vorpal blade went snicker-snack. He left it dead, and with its head, he went galumphing back. It's all about you, you know..."
One of my favorite quotes from the movie.
