SpongeBob SquarePants Season 3 Episode 13 Soap2Day
Mr. Krabs has Squidward direct a commercial for the Krusty Krab. When he finds out how much money Squidward is using, he decides to direct it himself. SpongeBob has a small (and I do mean small) role in the commercial. After the commercial airs (at 3:28am), SpongeBob thinks he is now famous and his ego gets twice as big.
