This is, like, an entire week's worth of internet WTF in one video. You'll watch this and think "That is so weird." BUT THEN IT GETS MORE WEIRD. Casting like this has NEVER been done before.
My favorite part is how Kathleen Turner didn't even bother to try and sing or lip sync. She's just all "Whatever. Is this thing being catered? Can I get some gin over here? And maybe some pastry creme?"
