I just rewatched “My Number One Doctor” – the Scrubs episode where Kelso signs up the hospital to use rateyourdoc.org
It turns out: it’s a real site! Not where you can rate real doctors, just where you can rate your favorite Scrubs characters.
“Colonel Doctor’s treatment can only be described as delicious and crispy.”
Dr. Kevin Casey still gets a 5 rating from me.
Update: There’s even a scene where Turk has the site open on his laptop. While blurry, it looks to me like the very same site.
