The King of All Media was upset over Howie's support of an oddity named Big Barry, a lounge singer whose rendition of Feeling Good was fine for a one-off laugh, but little else.
An enthralled Howie, -- describing Barry as a cross between Bob Dylan and the Easter Bunny -- told Barry that while he's not a particularly good singer, he's "an incredible novelty act" who audiences would pay to watch.
That was enough for Howard, who said his colleague's whimsical decisions left some of the show's standouts without a spot.
"The Howie filibuster is getting annoying to me, actually," Howard said. "I gotta tell you -- you know, Big Barry, this isn't about you. This is about Howie … and this is about the apology you owe to Flo Jo's daughter, to Andrew De Leon, to all the people that could have gotten through instead of Big Barry, you ruined their chance!

"Girls, girls, behave!" said Sharon Osbourne, while host Nick Cannon said, "You two go to your corners!"
