Can you link me this episode of House MD?

I can't seem to find the episode 'Ugly' anywhere. It's in Season 4 and it's the 7th episode of that season. If you could link me a site where I can watch that episode, free, without downloading or anything that would be great! Make sure the video works though, cause' I've tried a few MegaVideo videos and it always says 'This Video Has Removed Due To Infringement.' Thanks.
