The Stupor Salesman is a Warner Bros. Looney Tunes cartoon, directed by Arthur Davis, and written by Lloyd Turner and Bill Scott.

[3] Slug McSlug, a cunning canine criminal, pulls off a successful bank robbery using a bump key to gain entry.

Despite McSlug's attempts to rid himself of Daffy, the determined duck continues to intrude, employing unconventional methods to gain entry.

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.

Rarely, if ever, has one seven-minute cartoon burst its seams so thoroughly with inventive sight gags, throwaway jokes, and visual details.
