SpongeBob Squarepants is so funny!
Yes it is! For a show that came out nearly 20 years ago, it's done a great job holding up over the years
My mother-in-law thinks it's obnoxious, but it kind of grows on you when you figure out all of the characters.
It's very popular. It's the highest rated series to air on Nickelodeon, and the most distributed property of MTV Networks
I'm not really sure why.  Maybe people just really like how colorful it is.  The characters are well-developed, too.  I suppose that everyone likes a good vs evil plot.
Sometimes i think it's just the comedy. The first episode I watched was the "I ripped my pants" one, and I was instantly hooked.
Lol.  I've heard people say that there is a lot of references that go over the kids' heads.  I like how joyful and innocent SpongeBob is, and the music is catchy.
It makes sense that it's innocent. Hillenburg, the creator, compared Spongebob's personality to Pee-Wee Herman
