Other mistake: In "Violent Is The Word For Curly" (1938), the Stooges are mistaken for college professors. They are teaching a group of students at the all-girls school Mildew College to sing "Swingin' The Alphabet." During the song, the girls sing "Curly's a dope." The dean had introduced the three men as Professors Feinstein, Frankfurter and VonStupor - so how did the girls know Curly's name?
Other mistake: In "Busy Buddies" (1944), Curly pastes a Carrot County Fair poster onto a fence but has it upside down. In a close-up, the image of the poster is in reverse.
Other mistake: In "Dunked In The Deep" (1949), Moe, Larry and Shemp go to a pier where a ship is docked. The picture of the ship has been flipped and the ship's name, SAN CAPEADOR, appears in reverse.
Other mistake: In "Men In Black" (1934), the clock next to the loudspeaker always shows the time as 10:10. It never changes.
Other mistake: In "An Ache In Every Stake" (1941), when Moe and Larry fall out of their ice wagon and land in the street, it is obvious that stunt doubles were used. When the scene cuts from the doubles to the real Moe and Larry, Moe's legs are in a different position.
Other mistake: In "An Ache In Every Stake" (1941), Vernon Dent is running down a lengthy set of stairs as an icebox is rolling down above him. (The stairs were also used in the 1932 Laurel and Hardy short "The Music Box.") One scene of Dent running down the stairs is shown twice in succession.
