Meh...
RAB should've ended a while ago.
The very first one was the only one I actually found funny. After that you just added tons of unnecessary things. Cartoons aren't funny because they're filled with random cuss words and poop jokes. The jokes should be clever and witty. Not "Hey I think I'll randomly shoot glue in my ear. For pretty much the rest of this episode I shall be annoying as all hell and keep reminding everyone that I can't hear." The only part in this episode that I actually found funny at all was the cat saying that he slept in a bucket of nails in the attic.
Other than that one joke and the fact that the graphics are indeed good, this was lame. You need to take them in the same direction as in the first episode. They lived up to the name of the title and everything revolved around them being dumb. That was actually humorous.
(Oh and I must give you credit for making Satan so awesome. He's the one character left that you haven't completely fucked up. Please don't do so.)
