38 Fools in April

At the Krusty Krab, SpongeBob pulls numerous playful and harmless pranks on people. Squidward gets so annoyed that he pulls his own cruel and nasty prank on SpongeBob in retaliation. It ends poorly as SpongeBob runs for home, physically and emotionally hurt. Squidward goes to see SpongeBob to apologize, but finds it impossible to say "I'm sorry" to him. He is able to say it by putting a bubble over his head, so that SpongeBob cannot actually hear his apology. Squidward walks away, saying that his conscience is clear, but is confronted by memories of what he did. He goes back and genuinely apologizes to SpongeBob. Suddenly, SpongeBob fully opens his front door, revealing that everyone else is inside behind him, and witnessed Squidward's apology. Squidward states that he was fooling them as well before running away to his house while laughing maniacally.
