“There was a large mushroom growing near her, about the same height as herself; and, when she had looked under it, and on both sides of it, and behind it, it occurred to her that she might as well look and see what was on top of it.

[Alice] stretched herself up on tiptoe, and peeped over the edge of the mushroom, and her eyes immediately met those of a large blue caterpillar, that was sitting on the top, with its arms folded, quietly smoking a hookah, and taking not the smallest notice of her or of anything else.”

(From Alice in Wonderland by Lewis Carroll)
