Believe what you want. I think the evidence shows the contrary. His health problems have been known for some time now. The only difference now is we have a diagnosis.
Jim is going to watch the world burn while drinking, smoking, and fucking his big tiddied asian waifu. Ultimately, he will likely have a more dignified end than Ralph. Ralph is ever angling to watch the Killstream burn while not drinking, not smoking, and being fucked by Tyrone.
Also, I just want to add that CRP's idiotic comments about Jim's cancer was directly followed by CRP breaking his leg in a skydiving accident (see recent MATI episode). That makes me think God might be member of the Sweetie Squad. So, be on your best behavior. Lol.
