Cookoo Cavaliers is the 51st short subject starring American slapstick comedy team The Three Stooges. The trio made a total of 190 shorts for Columbia Pictures between 1934 and 1959.
The Stooges are unsuccessful fish salesmen. After becoming fed up with it all, they decide to go into the saloon business. When Curly tells a Mexican real estate dealer (Lynton Brent) their saloon has "...gotta have class and gotta have beauty," they end up with a beauty salon. Undaunted, the trio try their hand at giving a customer (Dorothy Appleby) a mud pack using, natural, real mud. After chiseling the cement off her face, the boys scalp three other Mexican beauties before having their bottoms shot full of holes.
- The working title of Cookoo Cavaliers was Beauty á la Mud.
- The "cookoo" in the title is often misspelled "cuckoo."
- In one scene, there is an unfinished gag involving hair remover being spilled on a dog. When Curly dries off the dog, the film cuts to the next scene. The unedited version shows the full gag-Curly wrings the dog out like a dishrag.
- Anita Garvin plays the woman requesting a weakfish. This was her last film, as she retired to raise a family.
