Secret Squïrrel said...: Ok, I looked it up. It's not what I would call well-known. The second word is "mathematician".; December 2, 2009 at 4:45 PM
Unknown said...: Answer : 1, 13, 2, 1, 5, 3, 2, 1, 4, 4, 7, 3, 1, 5, 3, 5, 4, 5

It is the number of letters in the words of the famous quote which is attributed to Charles Darwin:

"A mathematician is a blind man in a dark room looking for a black cat which isn't there"

so its completion is 4, 5 (or 5, 5 if you count the apostrophe); December 7, 2009 at 3:46 PM
