The following excerpt is from Alice and Wonderland, one of the most well known sources used for programming.

“she ran across the field after it [the white rabbit], and fortunately was just in time to see it pop down a large rabbit-hole under the hedge.”

“In another moment down went Alice after it, never once considering how in the world she was to get out again.”

“The rabbit-hole went straight on like a tunnel for some way, and then dipped suddenly down, so suddenly that Alice had not a moment to think about stopping herself before she found herself falling down a very deep well.”
