Hahahaha this made me chuckle so I thought i'd share. I went on YT today, just to test flash functionality with a new browser and OS, and I clicked on a random vid of the IT Crowd. And then got a screen with most of it upside down.
Wasn't quite sure what to make of it until I clicked a link on the page that said "Tips for viewing the new layout". It's not with every video, so not sure which ones you'd have to view. The one I was watching is called IT Crowd Series Episode I - Bullies.
Screenshots attached. Enjoy
