Here's mine

Season 1: I was a teenage Gary, i hate this episode it was boring, unfunny and creepy (culture shock a close second)

Season 2: Bossy boots, (to be honest it wasn't that bad i just couldn't think of a bad episode) ( None)

Season 3: Spongebob B.C, It was OK it just could have been alot better and funnier ( MM and BB 4)

Season 4: Good neighbours, It was boring, stupid, waist of time, incredibly annoying and repeatitive (Ghost host a close second)

Season 5: Fungus amougus, it had a stupid plot, increadibly stupid jokes and it was gross (TLAP close second)

Season 6: Penny foolish, Mr Krabs was out of character, boring and stupid plot (grooming Gary a close second)

Season 7: Growth spout, I don't like Pearl so this episode is bad and pretty boring and the ending sucked ( Shell shock a close second)

Season 1: Pickles

Season 2: Pressure

Season 3: Spongebob B.C.

Season 4: Gift of Gum

Season 5: Battle of Bikini Bottom

Season 6: The Splinter

Season 7: Growth Spout

Season 1:Culture Shock. I don't really hate any episode from this season, but I had a tie between this episode and Nature Pants for least favorite. They were both kind of boring, but I pick Culture Shock, because it was less interesting, and the ending was irritating.

Season 2:Bossy Boots. Once again, I don't hate it, but it was a little boring and irritating.

Season 3:The Great Snail Race.{With Ugh at a close second}. I hardly laughed at it, and it was irritating. Spongebob B.C was average but it was a little boring, and it felt really lazy and stupid.

Season 4:Best Day Ever. I thought it was really childish and a complete waste of time. It was a major letdown for a 25-hour marathon.

Season 5:Banned in Bikini Bottom: It was extremely boring, stupid, and childish.

Season 6:Spongicus. It wasn't funny at all, and it was also irritating.

Season 1: Pizza Delivery

Season 2: Squidville

Season 3: Sponge Bob B.C

Season 4: All That Glitters(All Those Tears), Ghost Host, and Best Day Ever

Season 5: Fungus Amongus, and Atlantis Squarepantis

Season 6: Gone, Pest of The West, and Dear Vikings

Season 7: Sand Castels In Sand(I know I'm going to get a lot of @#*% out of this), and Pets or Pests.

Hey? What are you staring at?

Here's mine:

Season 1: Mermaid Man and Barnacle Boy- I'm sorry, but personally I'm not a fan of MM and BB episodes even though a couple of them were awesome.

Season 2: This is a hard one. I'll say Survival of the Idiots just because it's overrated to me and frankly sort of gross. I don't really dislike it, though.

Season 3: Mermaid Man and Barnacle Boy 4- Like I've said before, I'm not a fan of MM and BB eps, and this one was ruined with its violence and bodily humor. You don't normally see this in earlier seasons.

Season 4: Um, Karate Island. It wasn't funny at all to me. The humor was forced, it was very creepy, and I have no idea how it got voted #1 in the Best Day Ever Countdown.

Season 5: It used to be To Love a Patty, but something happened to me recently that made me laugh at the scene with the fire the last time I saw it, so now it's Atlantis Squarepantis. It was overhyped, it focused mainly on the stupid tour, and there was too much singing and hardly anything funny and exciting about it at all. My apologies to the people who liked this episode.

Season 6: The Splinter- It was by far the most disgusting episode of Spongebob ever known to man, and it wasn't funny to me at all. Again, my apologies to the people who liked it.

Season 7: It was Chum Bucket Supreme for a little while, but now it's Sand Castles in the Sand. I used to like it okay, but now, frankly, I don't. It's extremely overrated and not funny enough in my opinion. It was also kind of boring to me, too unrealistic for my liking, and too out of character. Let's also not forget the fact that it had that gross gag, Patrick ripping off his skin. That was very disturbing and unpleasant. (look above at last sentence of my season 6 answer)

Season 1: IDK

Season 2: IDK

Season 3: IDK

Season 4: Good Neighbors

Season 5: Probably Battle of Bikini Bottom

Season 6: The Splinter (this is also my least favorite eppy)

Season 7: Probably Pets or Pests
