This Ghostbusters Afterlife T.V. spot is hilarious.

I saw this Ghostbusters: Afterlife t.v. spot and it absolutely put a smile on my face. I think it's the dark humor, with the "Stay Puft" marshmallows roasting each other and spearing each other with skewers. It's been a while since I saw the original Ghostbusters but I think that because Ray (Dan Aykroyd's character) chose the form of Gozer to be the Stay Puft Marshmallow man, that it has to remain in this form forever? Is that correct? Also, Paul Rudd is an actor that always brings a smile to my face. He's great in everything.
