Nostalgic old man, with a bit of wise and crazy thrown in.
When I did work experience at an old folks home with my high school class (community service is a graduation requirement for high school over here) there was this one old guy who told the most interesting stories about his youth and his family. His name was Nobby (awesome, I know), and the best stories were about his time in the Navy, the fights he got in, and all the chicks he went on dates with in his 20's. He was also a bit of a hip old guy in the sense that he knew quite a bit about whats popular today, and a seedy old guy in the sense that he always wanted to talk with and sit near the hot girls in my class.
