Car Talk, huh? Who knew. Landon Curt Noll [1] is a fairly well respected computer scientist and mathematician (sort of) who worked with John Horton Conway on the system for names of arbitrarily high powers of 1000 which was published in (Conway and (Richard K) Guy)'s book "The Book of Numbers" [2]. So he ought to know. Noll published a Perl script that formats integers into English names, and an online version is here: http://www.isthe.com/cgi-bin/number.cgi He spells "1001" as "one thousand, one" and similarly for everything up to 999999. For example 27101 is "twenty seven thousand, one hundred one" which has 11+8+13=32 letters and one comma. You can try more examples on the website. For the purposes of this question I think you can just break the digit into groups of 3 digits, add the letter-length of both, plus 8 for "thousand". - Robert Munafo [1] see http://en.wikipedia.org/wiki/Landon_Curt_Noll [2] Conway, Johh Horton.

I see that two versions of that sequence are already in OEIS: A092320 A126259. I avoided the standard spelling, because it's not clear how one should do it for arbitrarily large integers. [...]

On the program cartalk last week, there was a puzzle of the following form:
A list of numbers was given, and one was asked what they had in common (I give the actual puzzler at the end). The answer was that each of these numbers was divisible by the number of letters (excluding spaces) in the standard spelling out of the number in words. [...]
