Cruel Coincidence or Brilliant Foreshadowing?

In one of his last bonafide performances for the "Rodney Dangerfield TV Special: I Can't Take It No More" on November 29, 1983, Andy played a doctor by the name of Dr. Vinnie Boombatz, a heavy smoker who often kills his patients. Upon closer inspection, one can see that there's some more-than-coincidental symbolism in this suspicious skit. Here's the abridged version:

*THE SMOKING
In this skit, Andy puffs on cigarette after cigarette, something he rarely did...even in jest. The only other time he uses this prop is during his Tony Clifton act. Smoking causes lung cancer, which Andy would die of in less than 6 months despite being a non-smoker. What was he trying to tell us?

*THE "DOCTOR" FACADE
This was the only time Andy played a doctor or anyone in the medical profession during his entire career--doesn't it seem a bit strange that he did it less than one month before being diagnosed with cancer? More foreshadowing.

*PORTRAYAL OF THE DOCTOR
As we would find out soon after this show aired, Andy had an aversion to traditional medicine (hence his Psychic Surgery in the Philippines). In this skit, Andy portrays the doctor as a harsh, cruel "doctor of death" type, which was likely how he really felt about these so-called professionals. Again, his obsession with disease, death and medicine is hard to overlook.

*DEATH OF A PATIENT
Dr. Boombatz stands over a casket with one of his former patients as loved ones mourn. A congregation then swoops in and carries off the casket, BUT LEAVES THE BODY BEHIND. The depth of the symbolism here could fill a book, so I'll leave it up to you to interpret.
