Reading about Ellen Pompeo trying to justify her crazy "Punk'd" appearance reminded me that I never actually saw that episode, and have only heard about it.
So here it is on YouTube.
Frankly, she's not THAT crazy in it, so I don't know what the hubbub was all about. Sure, talking about how you could stab the waitress and watch the blood trickle down her face is kind of nuts, but it's not like she actually DID it.
OK. Yeah, she's nuts.
You'll have to sit through the annoying Ashton Kutcher introduction, and hopefully YouTube will work better for you than it is for me right now. I believe I am experiencing what is called a "buffering" issue. And I only hope there's some kind of salve available for that.
