Nobody. WOOT means "Hurrah (Wow, Loot!)" or "Want One Of Those"
go to fastpass tv. and from there, wootly or megavideo are the best links. :)
If you're in America you should be able to catch up on the channel's website. Otherwise, sidereel.com and watchseries.eu are good sites which display a number of links to other places where one can watch Grey's Anatomy. On those sites, Megavideo, Novamov and Wootly links are all fairly reliable and as far as I know don't give your computer any nasties, though Megavideo has those pesky viewing limits.
