There are times in the show where MPB seems like he’s very emotionally mature, almost the voice of reason when talking to one of the characters. Then there are times where either the butt of the joke or just really good at playing stupid. From his word plays, to his scatter brained ideas with Todd, to the crew neck/v neck discussion with Bojack. I think it’s just hard to know how to take his character
I think he’s just got adhd to an extent that makes him come across less unaware than he actually is. But then again I say adhd but like others have pointed out. It does seem to be the golden labs personality trait just exaggerated in the show
