Jefferson Airplane

One pill makes you larger, and one pill makes you small
And the ones that mother gives you, don't do anything at all
Go ask Alice, when she's ten feet tall
And if you go chasing rabbits, and you know you're going to fall
Tell 'em a hookah-smoking caterpillar has given you the call
And call Alice, when she was just small
When the men on the chessboard get up and tell you where to go
