"It's 4:11AM! It's four in the morning here....Screw you! I got up at four in the morning."It looks worse on the transcript than it sounds in the video.
I don't watch "The Today Show," and maybe its audience is especially fragile and doesn't get mock outrage, but this strikes me as pretty mainstream humor. It gets a big laugh from the crew. He continues because he's doing a humor routine. And when Matt Lauer says "cut his mike" in the end, he's joking too, isn't he? That's an allusion to this, right? That's the way I hear it.
