You can see that stunt on Cunning Works website (scroll down).
Everyone who thinks they actually mooned the moon raise their hand, I have a bridge you might be interested in....
For those keeping tabs back home, yes the "advertising on the moon" gag was probably first done in Franquin's 1959-60 comic book masterpiece "Z comme Zorglub" (Or if you speak Swedish, "Z som i Zafir") where Zorglub sends rockets to the moon to spell out "Coca-Cola".
His mistake though, was that all his little helpers spoke backward and had thus spelled the brand name "Aloc-acoC".
In fact Zorglub/Zafir is such a great over the top bad guy I wouldn't be surprised if Dr No was modeled on him. ;)
