Just want to throw in my 2 cents here and some of it has already been said:
Adam: I used to hate Adam but in recent years have come to really like his style of humor and have also noticed how very intelligent he is. His intellect is so quick and he can come up with something humorous in no time. He seems annoying, I think, because of his nasal, somewhat droning voice but his comments are usually right-on and funny. He even used a word (tumescent) that even Trump didn't know. But I agree that some of his jokes were not appropriate for the Buick men.
Michael: I got the feeling, like others here, that there was more to this than we were shown. Although I do believe that he wasn't comfortable running this event. Being a race car driver doesn't mean he knows that much about various cars but is good driving them very fast. It's entirely possible that he didn't want/or couldn't let his name be used for this particular car, for various reasons. Isn't that something that companies PAY people for? Why would he want to give it away for free? Also he may have confided to Trump that he wanted to go home because of his son dealing with the death of his good friend and this was semi-scripted.
Lou: all this time I thought he was used as the Hulk because of his strength....now I think it's because of his hair-trigger anger issue. He never adds any input into the planning except to show his muscles and then gets upset.
Trump and Little Donny: Both were total bullies and acted exactly like none of us like and complain about with school children. I hated the way he dismissed Tia (and that's the second time he's treated her badly).
The Women's Team: was awful and it's hard for me to believe that they won. But I am glad about Debbie's charity because it's one of mine also.
The Men's Team: ok but not great. Paul using the word "suck" was totally inappropriate for what they were doing. Better received in a high school auditorium.
I suspected right from the beginning that everyone would think that Michael should be the natural leader for this task and nobody used their brain to understand why he didn't choose to be PM, except Adam.
