When David Letterman rolled the video Tuesday, Dean's head appeared to explode at the end of the speech. "Did you see Howard Dean ranting and raving?" he asked the audience. "Here's a little tip, Howard: cut back on the Red Bull."
On his program, Jay Leno quipped: "I'm not an expert in politics, but I think it's a bad sign when your speech ends with your aides shooting you with a tranquilizer gun."
Jon Stewart introduced the clip on his show by saying, "That whole 'Dean anger thing,' it's a bum rap. The guy has his emotions under control."
