I've only seen one episode, but it was hysterical. There was a bully in school and he kept telling Spongebob, "I'm gonna kick your butt," in a really funny tone. I couldn't turn it off even though my 4-year-old was watching it too. Fortunately, he never picked up on the catch phrase.
I love Love LOVE the one where it's winter at Sandys house, and Sponge Bob and Patrick are playing in the snow and get locked in. And they shave off all her fur to keep warm
I love the bubble blowing episode where Spongebob is giving bubble blowing lessons to Patrick. I just howl every time Patrick does that stupid laugh of his, especially when SB blows an elephant bubble and Patrick screams "A giraffe!!!!"
I loved the one where SB was afraid of the Iron Butt. He was gonna stay inside for the rest of his life so he wouldn't get hurt. He'd just stay there with his friends--Chip (a potato chip), Penny (a copper penny), and used napkin (a used napkin). The first time I saw that one, it just cracked me up! Who thinks of this stuff??? LOL
