I Make POSES with me!
Spongebob> I'm the Open Window MANIAC!
Spongebob> Hooray Gary! We're finally HUGE!
(Random character after any accident/disaster)> My leg!
Some favorite episodes include the Snowball Fight, Rockbottom, Nematoads eating Spongebob's House, where they go to Sandy's dome when she's hibernating, Band Geeks (SCREEEEEEEEEEEEEEEAM VICTORYYYYYYY), where Plankton takes over Spongebob's brain...
I'll think of more later. Really great cartoon.
Edit: Invader Zim is indeed the cat's knees and bee's pajamas, all rolled up in a cinnabon of awesome and drizzled with erection juice.
Edit 2: Someone sig that. For I demand it. I mean, if you want.
