I agree with this. I'm certainly over analyzing it, that's for sure. I also think he tries to exhibit proper language. I just think he looks stupid when he goes through all the trouble of building the Proper Roy persona (sounding like a clown while he does it with all of his dadgummits) and then has it all unraveled by dropping a "bullshit" when talking about something that wasn't even his own timeout policy, or substitution patterns.
I realize this sounds like being sensitive to it because it was a Trump bash, but I did say I have no problem with him speaking out politically, and I assure you that if he had said something non-political like "Moonlight winning Best Picture is bullshit" I'd be calling his Proper Roy persona fraudulent as a result as well.
