I can't find anything to back this up, but I'm positive that when Flame Convoy (https://www.shmax.com/part_details/1749/flame_convoy) is alone, he pops out his extra heads and does Three Stooges routines with himself. He must, right? Wouldn't you if you had two optional noggins? (Photo courtesy of HighPrime, who prefers Joe Besser over Curly Howard and doesn't care who knows it.)
