Aren't you the guy with carnies in your family tree?
It's a dichotomy really. On my mother's side, my grandparents were circus folk. They were with the Strates shows during the 40's and travelled the northeast by train. After finishing his service in the marines my grandfather was the head tentsman, carnival barker, fire eater, sword swallower, strongman, and wrestled bears. My maternal grandmother was a burlesque dancer and they met at the circus.
My Father's side is a bit more prestigious but less fun. My great, great grandfather (my father's mother's father) was Dr. Albert Schweitzer, who won the Nobel peace prize in 1952, and worked with Bertrand Russell and Albert Einstein.
If you dig far enough, you may find some real interesting people in your family tree.
