I don't understand why the actress who played Charlie was even on this list. Nothing against the actress but she only was there for a little while, it should off instead have the characters of Susan, Treeger (the maintenance guy), Ben, Mr. Heckles, Dr. Burke (Tom Selleck), Frank Jr. Jr., even Paul Rudd was there longer, among others, just saying. Yes, I'm aware that the actors who played Dr. Greene and the maintenance guy are both sadly deceased now.
