It's everybody's favorite sponge! Up until now. ;(
For me, the last season I enjoyed was season 3, so I'm going to do a top 10 list of the episodes I liked.
Ten: Idiot Box
Such creativity. Such a dumb episode. I loved it. Squidward having no IMAGINATION was just hilarious, and the plot was nice, too.
Nine: Snowball Effect
IT's A BLANKET of great plot, originality, and jokes!
Eight: I Had an Accident
Oh my god! A gorilla underwater! Too bad the family closed the TV before showing where he went.
I'll finish the rest later.
