At the start, Moe Howard is standing at a window of the shop. If you read the lettering on the wall below the window it says "altercations " instead of "alterations."
One of four shorts from The Three Stooges to fall into the public domain after their copyright was accidentally not renewed in the 1960s-70s. The other three are Chaos vor Gericht (1936), Der brautlose Bräutigam (1947) and Arglist im Palast (1949). That is why these four shorts are always featured on low-priced Stooges videos and DVDs, usually of inferior quality.
Approximately two minutes in, Moe Howard is preparing to hit Shemp Howard while they are standing in front of a large radio. A portion of this scene is used during the opening sequence of the comedy/horror program Svengoolie (1995)
