Continuity mistake: In fake Shemp episode "Commotion on the Ocean" (1956), when the Stooges first greet the large villain on the ship, Moe's hat is flat and he wears an ascot. Instantly the shot changes up close and Moe's hat is poofed up and he's now wearing a necktie instead of the ascot. This was a combination of old footage with Shemp, and a new scene filmed with just Moe and Larry (after Shemp's death). (00:03:00)
Continuity mistake: In "Disorder In The Court" (1936), Curly is on the witness stand in a courtroom. When he tips his chair and falls backwards, a stunt double is used. The double's hair is much darker. When Moe and Larry rush over to pick him up, he is facing the wall. In the close-up, Curly is now facing forward. (00:05:00)
Revealing mistake: In "Busy Buddies" (1944), an angry bull knocks Curly over a fence. A dummy of Curly is used for the scene. As it sails over the fence, the hand of the crew member who threw the dummy is visible. (00:08:24)
Continuity mistake: In "Movie Maniacs" (1936), the Stooges unwittingly run into a lions' den. After they slam the door shut, Larry removes his top hat but in the next shot the hat is back on his head - and he and Curly have switched places. (00:14:46)
Continuity mistake: "Rusty Romeos," a 1957 short co-starring Joe Besser, is a remake of "Corny Casanovas," a 1952 short co-starring Shemp Howard. In a scene using stock footage from the earlier film, Moe and Larry are fighting, and a framed photo of Shemp is on a small table next to the couch. In the following scene, using new footage, the photo is of Joe. (00:15:10)
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?
Continuity mistake: In "Violent Is The Word For Curly" (1938), after putting the gas in the radiator of the car, Curly leans on the car and falls asleep. Moe walks up to him appearing to be almost instantly, but at that point the sun angle and shadows have changed quite a bit (indicating at least an hour or more between takes) even though it took place in a matter of a few seconds.
Plot hole: In "Violent Is The Word For Curly" (1938), the stooges start singing "Swinging The Alphabet." After Moe starts, he has the girl students join in on the song. Some mistakes follow - first, after a few letters are sung, ALL the girls together change to a higher note and faster tempo (which is impossible since NONE of them knew this song before - let alone ALL switch notes together). Also, they all sing "LA LA LA" backgrounds suddenly when Curly sings solo again ALL at the same time.
Revealing mistake: In the episode "Hoofs And Goofs" (1957), just as Birdie (Moe in drag) is coming out of the kitchen, a fake Moe's face is revealed from the side as he's walking away (used to replace Moe since the real Moe was playing Birdie in the same frame).
Character mistake: In "Boobs In Arms" (1940), the Three Stooges are in the Army. On the back of Curly's uniform is an advertisement for "soup, salad, entree, coffee, desert" at O'Brien's Kosher Restaurant. "Dessert" is misspelled.
Continuity mistake: In "Disorder In The Court" (1936), Curly is trying to catch a parrot flying near the jury box. He tries to hit the bird with a mallet but winds up knocking out the six jurors in the front row. Moe drags Curly away, but suddenly the six jurors in the back row also appear to be knocked out.
Visible crew/equipment: In "Playing The Ponies" (1937), a man eats a handful of hot pepperinos, and his mouth is burning. He quickly drinks a large container of water. The hose that drained the container is visible below his right arm.
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.
Plot hole: In the episode "Scheming Schemers" (1956 - fake Shemp episode) at the start of the episode, Moe is given the address for a plumbing job over the phone and he and Larry take off in their jeep - accidentally leaving Shemp behind. Next scene, Moe and Larry are in the house working on their plumbing job and minutes later Shemp just shows up outside in a separate vehicle. Shemp would not have known where the job is since he was left behind and never would have known the address Moe and Larry went to.
Continuity mistake: In the episode "Scheming Schemers" (1956), Larry and Moe start to dip their heads towards each other in the sink and suddenly the camera changes to a more central angle and the two start over in dipping their heads towards each other.
Continuity mistake: In "Calling All Curs" (1939), Moe accidentally punches Larry in the face. Larry falls to the floor unconscious but in a later scene he is sitting on the floor with his back against a wall.
Continuity mistake: In "Some More Of Samoa" (1941), the Stooges are on the island of Rhum-Boogie and Curly is wearing a tiger skin. In the final scene, as they hop into their canoe, he's suddenly wearing a leopard skin.
Continuity mistake: In "False Alarms" (1934) Curly ducks when Moe throws a bucket of water at him and the water lands on the fire captain who is standing behind Curly. In the next shot, the captain's uniform is completely dry.
