Who's on First? The line, "Who's on First?", was ranked No. 91 on
American Film Institute's
100 Movie Quotes. The "
Who's on First?" scene was intended to appear much earlier in the film. Costello begins the routine by saying, "When we get to St. Louis...", but at this point in the film they are already in St. Louis. Members of the film's crew can be heard laughing off camera during the routine.
Other routines The film also contains the "Lower/Higher" routine, where Costello auditions as a singer while Abbott shouts directions to the stage crew to change the height and placement of the backdrop curtain. Costello believes Abbott is directing him, not the stagehands, and follows Abbott's instructions by singing higher or lower, or even on one foot. Bonita sneaks poison into Lou's wine, leading to the old swapping of glasses routine (previously done by Abbott & Costello in
Pardon My Sarong). Costello accidentally bakes feathers into a cake, which is served to everyone in the saloon. The patrons wind up coughing up a blizzard of feathers. This gag was taken from the
Three Stooges short
Uncivil Warriors (1935). Costello and Sawyer perform the "Mirror Scene," copying each other's actions. Variations of this old vaudeville routine were done by several movie comedians, most famously in the 1933
Marx Brothers film
Duck Soup. Abbott and Costello had used it before, too, in
Lost in a Harem. To break up the crooked card game and rescue Captain Sam, Abbott concocts a plan to dress as a bear and scare everyone out of the casino. Costello ends up wrestling with a real bear, thinking that he's wrestling Abbott in a bear suit. There is also a variation on the
"Niagara Falls" routine. Dexter and Sebastian sneak into Bailey's room while he is asleep to search for incriminating evidence. Bailey has a sleepwalking nightmare where he imagines he is being attacked by Indians, resulting in Sebastian being repeatedly throttled. Abbott and Costello also eat a meal that was prepared in a kitchen with stray cats roaming and meowing leading them to believe they are eating cat when the meal is ready. This also appears in
Malice in the Palace (1949) from the
Three Stooges. ==Production==
