Spider-Man S01E19 - To Catch a Spider/Double Identity

Under the guidance of Dr. Noah Boddy, the Green Goblin, Electro, and the Vulture join forces for revenge on Spiderman. In a confrontation with Noah Boddy's three stooges, Spidey practices ventriloquism to cause each of the three miscreants to think that he is being insulted by the others, and the excitable trio of villains begin fighting each other. 

Art robberies are committed by an old enemy of Spiderman, actor Charles Cameo, who can utilize masks and make-up to usurp any identity, including those of J. Jonah Jameson and Spiderman!
