Robert Schimmel
Schimmel wasn’t the type of comic who’d find himself on network television. His material was profane, dirty, definitely NSFW, and too personal for everyone’s liking. Hence, he was a mainstay on HBO and the Howard Stern Show.
Through his life he suffered through several divorces, lost his son to cancer when the boy was only 11, and suffered from cancer. He also developed cirrhosis of the liver due to a blood transfusion from his days in the Air Force.
While on the list for a new liver, he was in a car accident, and died.
I was just going to comment on the math but you beat me to it.
