Also I sent money that gives me the right to tell Wes he is a dumbass who should have made better life choices.
You guys are missing the subtle genius of this.
Brian, fearing the worse for our man Wes, pulls out all the stops to display his far worse terminal case of Brian. He lashes Wes with arrogance, narcissism, ill timed financial advice and judgement. Adds a dash of attempting to steal his thunder with claims of having cancer himself and really, who doesn't read it and seriously think "Would I rather be Wes than Brian?".
Forget having cancer - imagine being cancer and claiming to have cancer.
It could be worse Wes, it could be worse.
