Quoth PB: "It's complicated... He was the first of my experiments gone wrong."

My guess is that his brain functions in a very similar manner to the brain of somebody with high functioning autism or Asperger's (thus explaining the social issues, lack of indoor voice/regularity in speech, and obsessiveness)... and he's also an idiot. A weird idiot. A weird idiot who's also a jerk and has quite a liking for bland foods. And a long tongue.

Even if PB fixed whatever mental ailment he suffers from, he'd probably still be a doofus to some extent.
