Cookie (Dude, Where's My Ranch?)

Cookie is the rancher that the Simpson family met at the Lazy I Ranch.

History
Cookie was a good friend to the Simpsons. He invited them to dinner and lived with them. He died at some point when the family were at the ranch, shown at the end when Marge points to his gravestone. It is possible that he was the rancher who Rich Texan mentioned having accidentally killed after the dance.
