I entered them all, it played an ad via the youtube clip the first few comps I entered and the word was displayed at the bottom of the ad after 5 seconds or so. Now the videos are just the codes for me, must have watched all the ads :p
Certainly unique, had never seen it before either.
That has to be the worst captcha type thing ever. It's meant to tell you some code while you watch an add, did anyone see a code?
