How?
The trick is that you look at how many characters a word contains. E.g. everything contains ten characters. Ten contains three characters. Hence ten is three. Three again, consists of five characters. Five uses the magic number of four characters. Four has four characters and is thus four.
It is as simple as that.It works because four is the only number with the same number of characters as it's value. All the other values converge to four at a given point.
Other languages
Four works
English isn't the only language this works with. It also works in Dutch (vier = 4) this is also the language I heard of it originally since I'm Dutch :) and German (vier = 4). A thank you to James who pointed out some typos in the original German counting words on my site, they have now been corrected.See 0 to 100 in English, Dutch or German.
I received an e-mail from Doron Seijffers who pointed out to me that everything is also ארבע = 4 in Hebrew, thank you Doron.
Kind of works (Four is not quite 4)
It kind of works in Croatian, Czech and Italian, but everything in any of these languages is 3 (= tri, tri and tre).Thanks to Sarah-Jane Clarke who pointed out a mistake in the Italian counting numbers and to also thanks to Fred and Dany who answered my questions about the Italian counting numbers.
Mihai Ghimus send me an e-mail that everything in Romanian is 5 (cinci). Thanks Mihai.

Doesn't work
There are also some languages (in alphabetic order) in which it doesn't work at all.new! Ove Saeth emailed me how to count in Chinese. Everything is either 2(=er) or 3(=san). Thank you, Ove for this additional language.

In Danish everything is either 2(=to), 3(=tre) or 4(=fire).
Tnx to Karsten Jensen who mailed me the Danish word for 0 which wasn't in my old Danish/Dutch dictionary :). Also tnx to Christian Ravn who pointed out that you write the Danish counting words as one word. (e.g. syvoghalvtreds not syv og halvtreds).

For a moment Jari. T. and I thought that everything in Finnish was 5. Unfortunately we then noticed that you often end up in an endless loop between 8 (kahdeksan) and 9 (yhdeksän). Thank you Jari T. for letting me know the counting words in Finnish!

In French you'll end up in a rather long loop since 4 (quatre) => 6 (six) => 3 (trois) => 5 (cinq) => 4 (quatre).
See proof or 0 - 100 in French.
I used to have Hungarian listed as a language where everything was 4 (= negy), but Tamas Tenyei -who is Hungarian- pointed out to me that you often end in a loop between 5 (öt) and 2 (kettö), something I failed to notice while I was checking the Hungarian dictionary. (Thank you Tamas for letting me know).

Japanese: browsing the internet I came across a Japanese language website. A quick check showed that you either end up on 3 (san) or 2 (ni) -- please insert funny Monty Python joke here --

�ystein Bj�rklund-Lassen e-mailed me that counting in Norwegian is very similar to counting in Danish everything is either 2(=to), 3(=tre) or 4(=fire). Thanks �ystein for sending me all Norwegian counting words from 1 - 100.

In Polish it doesn't work either. 4 (cztery) => 6 (szesc) => 5 (piec) => 4 (cztery).
See proof or 0 - 100 in Polish.
In Portuguese also ends in a loop, although only between 6 (seis) and 4 (quatro).
See proof or 0 - 100 in Portuguese.
In Russian 4 (=I think my keyboard is broken 'cause I can't find the Russian characters on my keyboard ;-) has 7 characters and 7 has 4 characters). You are eventually stuck in an endless loop.
In Spanish everything is either 5 (=cinco) or you end up in an endless loop between 4 (=quatro) and 6 (=seis).
See proof or 0 - 100 in Spanish.
In Swedish everything is either 3 (=tre) or 4 (=fyra) which makes it a bit hard to decide.
See proof or 0 - 100 in Swedish.
Everything in Turkish loops between 3 (=üç) and 2 (=iki) which prevents it from ever becoming four.
See proof or 0 - 100 in Turkish.
Robert Bruce e-mailed me a while back that everything in Welsh was an endless loop. Huw Tegid of www.linklinewelsh.co.uk was kind enough to send me a very detailed description of counting in Welsh, even though his replies got lost in my spam box twice. In Welsh a word either ends up being 3 (tri) or 6 (chwech).

I tried to be as precise and accurate as possible, but as you can see from the revisions, my inferences from the dictionaries aren't always 100% correct. So if you happen to spot a mistake, please let me know.
