KC seemed like damaged goods during his last couple of visits. He was a sad figure and without his bumbling youthful image all his charm is gone. I wouldn't mind him back but I don't think he could bring the same magic to the mix he used to - and even if he could would he be able to get the goods passed the fun killers Howard and Gary?
As OP says, I would still take KC, or Will or Jason, over Booey. Booey is screwing the pooch. He has shown over and over that he can't think outside the box that Howard created for him in the middle 90's that had Howard as an all important cog in the creative machine. Howard recused himself long ago and Booey never adjusted. Booey has trouble getting face time with Howard for sure but he has the perfect platform on the WUS to introduce bits to the HSS besides fake staff fights and he let's those golden opportunities pass every day. Another perfect example of his bad producing was the recent "Newlyweird" game. It wasn't Booey's fault Howard was completely unprepared and made a fool of himself reading those questions, but it felt like it was the first time Booey heard the questions too. Booey needs to be doubly prepared to help coax his star along - how can that not be his default mode by now? I know it would be for Jason.
