Due to a stock footage error, Shemp's picture is seen on the table, instead of Joe's, during the scene where Larry repeatedly smacks Moe on the head with a shovel.
The shading of the davenport couch cloth changes from a lighter to a darker shade in-between shots.
When Larry and Joe are pulling the tacks out of Moe's behind, a dubbed-in yell of Larry's is heard instead. Again, this is a stock footage error.
