[quote name='Z-Saber']Without taking two seconds to look it up on IMDB, I know his voice changed, but I figured it was still Tom Kenny. Someone earlier said the originals left, and I'm wondering if they meant the original production crew or voices? Anyway, they pretty much started sucking right after the movie came out. The movie was fantastic, but the episodes that followed it sucked.
Nowadays, I only watch it if it has the "old" Spongebob voice (which, like I said, I don't know if Kenny just changed the way he sounds or it's someone new) and I immediately look for something else if it's the "new" voice.
Fairly Oddparents is freakin' awesome, as well as Avatar. Those two and Spongebob are the only cartoons I ever watch.[/QUOTE]
The voice cast has never changed in Spongebob. It's just that the show's been going for 8 years, so it's only natural some voices would change subtly along the way.
Besides, everytime you hear Spongebob laugh, that's Tom Kenny hitting his throat really hard. Which is bound to have some long term problems.
