Reception:
Animation historian Mike Mallory writes, "There is not a wasted cel in The Stupor Salesman. At first glance, the story of a bank robber who cannot escape the diabolical persistence of door-to-door salesman Daffy Duck (at his stream-of-consciousness best) sounds like a conventional pest-vs.-threat cartoon, but it is not. The short zooms by with the insistent pacing of the early Warner Bros. gangster films it aggressively parodies. Rarely, if ever, has one seven-minute cartoon burst its seams so thoroughly with inventive sight gags, throwaway jokes, and visual details."
