The D!ck Head stamp will never not be funny.
I always thought the completely random "hates women" was killer funny, just the peas of resistance on that whole thing.
My take on Tang-
I worked for a guy once, he came in from outside and he was kinda weird dude, but fine. Quirky maybe, but a decent boss, good guy, and knew the business.
Then HE got a new boss, who didnt know our biz at all but was determined to "drive results". He put a ton of pressure on my boss and after some months he just cracked. He became angry and aggressive, dismissive and insulting. Just a total ahole. He got in the face of one of my direct reports and my guy damn near punched him! It was bad. Eventually he got a different job and left the company.
Anyway, i think thats whats happened w Tang. I think he was a great asst coach, but now all the pressure and focus on him has overwhelmed him. And so he has flipped out, got weird, and turned into an ahole.
