Out of curiosity I googled "Skor de Gaulle" last night and was amused to note that just one day after the gag originated here, it now appears on dozens of websites (mostly football forums but joke websites too) from here to Australia, with some posters mentioning that they received it by text. It's appeared on an Iranian sports site, and also on foreign language forums in Belgium, Norway, Portugal and Turkey. Interestingly the majority of instances refer to Arsenal trying to sign the 3 Belgians, which is a neat adaptation given their predicament.
The power of the internet, eh? Now I can just sit back and let the royalties roll in........
