Now, THIS is an example of a good Krusty Krab episode. (Just watched it online)
It feels like Drive-thru to me. It has a simple plot, where anything starts to break down, and it's done very cleverly. The characters act perfect, especially Mr. Krabs- I mean, he's cheap, he was always like this, but at least he has common sense (and that's something you don't see very often in new SB).
Now, it's time to watch it's counter part Krabs a la Mode.. Those two are rated reaaaallly high (9.6 for this and 9.7 for Krabs a la Mode).
