The Stooges are janitors in a doctor's office working the night shift. The usual antics occur, first with Moe getting an electrical shock down his pants, leading to a cossack dance. Then, Curly gets his head wedged inside a fish bowl, containing a live fish. Though Moe and Larry eventually slide the bowl off, Curly starts to feel the swallowed fish tickling his insides. Moe manages to fish the aquatic critter out of Curly.
