From "Alice in Wonderland" by Lewis Carroll (pen name of Charles Dodgson)
"...the hot day made her feel very sleepy and stupid ... she was just in time to see it pop down a large rabbit-hole ... The rabbit-hole went straight on like a tunnel ... she found herself falling down a very deep well... 'Do cats eat bats?' 'Do bats eat cats?' ... ' Oh, how I wish I could shut up like a telescope!'... Alice opened the door and found that it led into a small passage.... she tried to imagine what the flame of a candle is like after the candle is blown out......."
