This is: Dr. Carey Flabunschtoigan.
Those who think themselves clever call him Corpulent Carey. He is owner, operator, and overseer of that overly audacious cavalcade of characters (and cats) known simply as the Hobo Miniature Circus. His huge lungs (with the assistance of a wholly hidden moustache microphone) assist him in assailing the audience with whimsical wailings of wimsy and wit. Not to mention an assailment of alliteration.
