Here's an odd idea, to see it simply search for # DouptoYoutubeBanner on youtube. (or click that working link so you don't have to type so much). Ad agency twentythree in Israel - the guys who kidnapped Alex Bogusky's facebook page remember? - created this little stunt for Doupto.com. Now all they have to do is solve the issue of having the target search for the "DouptoYoutubeBanner" on youtube. I don't think you guys reading this are it.
