The first three are the best. Season four started off good but then it brought us those terrible episodes from the Whale of a Birthday (DVD) which are probably the worst SpongeBob episodes in my opinion. Seasons five onwards have their own ups and downs. They aren't as good as the first three, but they still brought us some good episodes.
Hey this is my list
1 The Splinter (I had a scab bigger than my hand on my head!I had a lot of splinters not as bad as that one!)
2 House Fancy (it showed blood)
3Gary Takes a Bath (too dull for me)
4 reef blowers (where's the funny part)
Alright, why hasn't anybody mentioned Face Freeze yet. It would be a good episode, but alot of the work that went into it was in the ugly faces, if you ask me. I just think it would be better if they focused a little bit more on the plot.
