SpongeBob SquarePants, Season 5

Mr. Krabs:
SpongeBob, what's the meaning of this?

[SpongeBob inspects a plate and then notices a spot and screams]

SpongeBob:
SPOT, SPOT, SPOT!

Mr. Krabs:
That's right, a spot. You know the rule. Nobody leaves work till...

SpongeBob:
...till everything's ship-shape, sir. Don't worry, Mr. Krabs, I'll get this plate cleaned up in a jiffy.

Mr. Krabs:
Oh, and, uh, lock up when you're done.

SpongeBob:
Lock up? Wait, Mr. Krabs. Don't you remember what happened last time you left me here alone?

[Flashback when the Krusty Krab is on fire, Mr. Krabs was shedding his tears. We cut back to the present]

Mr. Krabs:
Should've never left you alone with a lit blow torch and me roller skates. But, since I've removed all the welding equipment from the premises, there's no-ho-ho chance of that happenin' again, right? Now, get to work.
