What's your favorite Spongebob episode?

Thirding Band Geeks, that was the highlight of my childhood. Great visual gags throughout, and it's nice to see Squidward come out on top for once. Also Squilliam was absent from the show for so long I thought he was dead.
I also really liked Frankendoodle and I Was A Teenage Gary for the absurdity.
- Is mayonnaise an instrument?

Off the top of my head:
Rock Bottom
Krusty Krab Training Video
Squid's Day Off
Idiot Box

The one with the magic conch.
Or the one where SpongeBob goes into other people's dreams, but really just the squardward one.
- Oh yeah, when Squidward dreamed about blowing SpongeBob.

Graveyard Shift.
I never liked night shifts. But I loved the vibes. And this episode oozes that.

Rock Bottom S01E17b: wherein SpongeBob gets on the wrong bus and ends up in the deep
Band Geeks S01E15b: wherein Squidward forms a band to play at the Bubble Bowl
Graveyard Shift S02E16a: wherein Patrick and SpongeBob are scared of the hash slinging slasher
Bubble Buddy S01E03b: wherein SpongeBob creates an anthropomorphic bubble person to act as his friend
- We weren't allowed to watch Graveyard Shift when I was a kid because it scared my little brother 😂 it was years before I learned the Hash-Slinging Slasher was just some guy

There's a time travel one that I've seen tons of times. and also a Christmas one I remember the song of. Sorry I can't remember the titles

The episode where Squidward was searching his Clarinet in a small Tresor which he must share with Spongebob... but spongebob made a huge Harry Potter like Room in that small thing. Squidward was searching it inside there. Going from hint to hint into an LSD trip like adventure.
