Summer Job - S7-E18
Continuity mistake: Mrs. Puff didn't know that SpongeBob works at the Krusty Krab, when she already found out in 3-18 "Krusty Love." Even stranger thing, Mr. Krabs and Mrs. Puff have no idea who each other are, but they also already met in that episode.
Fools in April / Neptune's Spatula - S1-E19

The Bully / Just One Bite - S2-E17
Continuity mistake: In the episode "The Bully," when Flats punches Spongebob, Spongebob states to Gary that he's made out of some spongy material, that it absorbs his blows and it doesn't hurt him at all. But in later episodes, when Spongebob gets knocked out that never happens anymore.
Procrastination / I'm With Stupid - S2-E19
