I guess that ends any hope of Ghostbusters III coming out.
I don't know if "Fat Egon" would have worked so well for me. I don't know if it had anything to do with his medical condition, but he sure bulked up a bit over the years.
Have you seen Dan Akroyd? I think he ate the Stay-Puffed Marshmallow Man.
That whole gang (Akroyd, Murrey, Martin) are the age where weight is very difficult to control. It started for me at around 42. That's when just breathing seemed to add pounds. On top of that, it is much harder to lose weight now. Youth is wasted on the young. 8^)
They also have a number of other strikes against them when it comes to weight gain. Over 60, not as active as they used to be, cleaned up their drug issues and settling into retirement/grand kids. All of these add up to lots of extra weight if you are not very, very careful.
