SpongeBob SquarePants, Season 1

SpongeBob:
I don't get it. I made my house a mess, which was making it clean, which made Squidward clean my yard, but that really means he's messing it up. But the opposite of clean is filth, which means filth is clean, that means Squidward is really making my yard a wreck, but I normally wreck my own yard which means, Squidward is being the opposite of Squidward, which means he's SpongeBob! A-ha! I understand everything now! I must be the opposite of SpongeBob, by being... [Disguises himself to look like Squidward; talks like him] Squidward.

Patrick:
Hey! I wanna be opposite, too!

[SpongeBob puts some coral on Patrick to give him a Squidward nose.]

Patrick:
Yeah! Finally! Yoo-hoo! I'm Squidward! I'm Squidward! Squidward, Squidward, Squidward!

SpongeBob:
Wait. It's not enough to look like Squidward to be opposite. [mimics Squidward] You have to act like him too. Boy oh boy, do I like playing the clarinet. I practice and practice all day long but I never get any better. [own voice] Now you try.

Patrick:
Okay. [inhales, beat] I'm Squidward, Squidward, Squidward, Squidward!

SpongeBob and Patrick:
I'm Squidward. I'm Squidward. I'm Squidward, Squidward, Squidward!
