When Steve tries to come up with an idea for a school talent show act in "The Talented Mr. Dingleberry" after his singing is sabotaged, Roger pitches becoming his ventriloquist dummy. He shows off a scrapbook of his former act which includes several game show appearances. Later, when Roger turns more psychotic than usual, Steve discovers that the scrapbook also contains clippings from where his former partner Dennis was blamed for a series of murders and sent away to the Danvers Asylum for the Criminally Insane.
