SpongeBob SquarePants, Season 9

Charlton Hawkfish:
This is what you get when so-called fish kind in all its hubris and ignorance stoop so low... [points to Mr. Krabs and Crupski] ...as to cut corners in its plumbing system! Extinction is the result of being cheap!

Mr. Krabs:
What a bunch of malarkey.

Charlton Hawkfish:
At least we didn't waken the great sewer snake. [sees the sewer snake behind him as he looks up] Check that.

[All of the customers run out of the stadium upon seeing the sewer snake, but Charlton does not go back down. He throws the axe, pulls up he sleeves, and runs heroically towards the snake. However, he has an idea on how to defeat it. He points to his nose.]

Sewer Snake:
[with a squeaky voice] Uh-oh.

[Charlton pokes the snake with his pointy nose and the snake yelps and flies around like a balloon and falls back through the hole and into the sewers. Back at the Krusty Krab, the toilet erupts with water and floods the restroom. The water bursts out of the restroom with the safe covered in filth. The safe is opened by Squidward who along with SpongeBob are covered in sewage.]

Squidward:
Hey, everybody. The cook's back from the toilet.

SpongeBob:
Who's hungry?

[All customers then burst out from the Krusty Krab, screaming and freaking out, as the episode ends.]
