Fortunately I've been doing a lot of catching up lately by watching some more SpongeBob episodes I haven't seen yet by watching a lot of DVD's and tapes one of my friends has over his house, so now I've seen about 100 episodes. Anyway, let the scoring begin!
Season 1.
Best episode: tough decision between Pizza Delivery and Valentine's Day.
Worst episode: Sandy's Rocket.
Season 2.
Best episode: Christmas Who?
Worst episode: Bubble Buddy. (There's just some parts of it I don't really like but I do like the scenes that feature boo-boo keys and snake eyes and the ending.)
Season 3.
Best episode: Top 3 all-time favorites: Chocolate with Nuts/Graveyard Shift/Krusty Love (and the movie if it counts.)
Wosrt episode: I have a hard time choosing one too.
Season 4.
Best episode: Patrick SmartPants
Worst episode: (This one's easy)-Good Neighbors.
Season 5.
Best episode: Friend or Foe?
Worst episode: There was actually quite a bit of epiosdes in this season that I found suckish, but if i had a most hated episode and least favorite of all time for this season it would have to be Fungus Among us which i saw at my friend's house yesterday and he also didn't like it either.
Season 6.
Best episode: House Fancy 2nd place: The Patty Caper.
Worst episode: Penny Foolish 2nd place: The Krabby Kronicle. (Two episodes I haven't seen yet in this season are The Splinter and Giant Squidward.)
Those are my favorite episode(s) out of each season. (And least favorites.)
