I'm also surprised that Ralph is smarter than he looks.
Someone and I elsewhere once joked that maybe Ralph has supersanity. lol The whole "he's more than he seems" thing's been subtly hinted at a lot over the show's history, I like to think he's meant to be more one of those very "different" kids who's kind of not in the same world as everyone else, and certainly not a retard like some think. That's what makes him fun.
Well it wasn't what I was expecting. They advertised that this was Ralph-centric like crazy but he only comes literally in the last three minutes of the episode. So...I feel a bit dissapointed over that. I was looking forward to seeing how his Dad would take it all, or maybe even Quimby. Maybe see a little bit of the emnity between those two again over it but they barely appear too. It's really more a 20 minute political agenda venting using this show's setting and characters as a disguise than a full blown episode. It's even very 4th wall...from Jon telling Krusty he'll "remember him like he used to be", to Homer making tones of out of show self references, to Ralph winning Lisa over to his side and all that stuff in the end just like that. It's really almost more a message about the upcoming election than a story or even a satire.
