Sailor Mouth / Artist Unknown - S2-E15
Continuity mistake: "In Artist Unknown", when Spongebob creates the statue, the right arm of it is tucked behind it's back and the left arm is bent with the hand resting on the chin. When the art collector jumps onto the head to remove the nose Squidward placed on it, the arms are switched so that the left arm is behind and the right hand is up on the chin. Then, when the art collector carries the statue out, the arms are back in their original positions.
Sailor Mouth / Artist Unknown - S2-E15
Continuity mistake: In "Sailor Mouth" when Spongebob starts cussing in the Krusty Krab, a sailor and a pirate make a comment, but when everyone leaves the Krusty Krab, the sailor and pirate are nowhere to be seen.
Chosen answer: You need to provide a little bit more information to be able to answer a question like this. In what region is it not being shown? I see it being replayed here in Australia fairly frequently. As for a general reason, there does not appear to be any for why it specifically might have been taken off the air in any country or region. Like any show certain episodes can sometimes not be replayed for long periods for unknown reasons.
