Scheming Schemers is a 1956 short subject directed by Jules White starring American slapstick comedy team The Three Stooges (Moe Howard, Larry Fine and Shemp Howard). It is the 173rd entry in the series released by Columbia Pictures starring the comedians, who released 190 shorts for the studio between 1934 and 1959.

Plot

The Stooges are all-night plumbers, hired to retrieve a valuable ring that fell down a drain at the opulent Norfleet mansion. Mr. Norfleet is hosting an elegant party and hopes that the plumbers won't disturb his guests. Despite initial success in locating the ring, Larry inadvertently propels the jewel back down the drain. The Stooges investigate the plumbing in the basement, and make matters worse by confusing the water pipes with the electrical system. The ensuing spectacle causes water to cascade from unexpected sources. Meanwhile, Shemp goes upstairs with his tools to work in the bathtub.
