Continuity mistake: In "Self-Made Maids," Moe, Larry and Shemp play dual roles, appearing as artists and as three models, Moella, Larryella and Shempella. In one scene, Larryella squeezes Shemp's hand while he's holding a tube of black paint. The paint squirts only on his face but in the next shot there are also paint spatters on his smock. When he returns to his easel, the paint on his face and smock has disappeared.
Character mistake: In "Movie Maniacs," the Three Stooges arrive in Hollywood via train, sneak into a movie studio and walk onto the set of a movie being filmed. A starlet looks at Curly and says, "Oh, Mr. Howard." There is no way she could have known his name.
Revealing mistake: In the episode "Disorder in the Court" (1936), Moe and Larry start playing Tic Tac Toe on the prosecutor's chair with chalk and Moe first puts "X" on the upper left square. The prosecutor then sits down on the chair and when then standing up to object, the marks which copies on to his jacket from behind don't match. The "X" is gone and shows an "O" in that square where it should have copied the "X".
Continuity mistake: In the episode "Scheming Shemers" (1956), after Moe reaches into his tool bag to get Larry out of the drain, he holds a plunger in his left hand and a wrench in his right hand. The camera suddenly changes angles towards the sink as Moe arrives and now the plunger and wrench are each held now in the opposite hand instantly.
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)
Revealing mistake: In the shorts "In the Sweet Pie and Pie", and "Disorder in the Court", when there is stunt to be done that would hurt Curly, the stunt double is easily identified.
Woman Haters - S1-E1
Visible crew/equipment: At the end as the boys were old men, the shadow of the boom mic can be see on the curtains behind them.
Continuity mistake: In Malice at the Palace, after the fruit is wiped away from the guard's face, he turns to look at Moe. After a quick cut, the man repeats looking at Moe.
Continuity mistake: In "Malice in the Palace", the big guard menaces Shemp until Shemp starts flinging fruit with a sword. Before the first piece of fruit hits the man's face, his face was clean, then there's remnants on his face, suggesting multiple takes.
Continuity mistake: In the episode "Malice in the Palace", Larry drops a hot dog after plating them, and never notices. After setting the cat up with a hot dog, the one on the floor, along with the small amount of water, has disappeared.
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.
