In this classic, The Great Man (W.C. Fields) portrays Egbert Sousé (accent grave over the “e”), a small town layabout, who spends his happiest hours downing cocktails at the Black Pussy Café. After accidentally disrupting the getaway of a couple of bank robbers, Sousé is rewarded with a job as a security guard and is soon involved in embezzling bank funds. The paper-thin plot serves as a framework on which to hang a number of alcohol-fueled gags, including a memorable sequence in which Fields slips the bank examiner a Mickey with the help of the Black Pussy’s bartender, Joe (Stooge Shemp Howard).
