You know Donald Rumsfeld's address is available online?
Why do I know this you (and the Secret Service) might ask?
When I couldn't find my kid after his flight landed in Detroit, we were joking at work about calling Rumsfeld and getting him to locate him for me. So, we punched his name into yahoo, and it didn't come back, but did direct you to that "people search" feature where you pay $14.95 and there he was.
I didn't pay it, so don't know his actual address, but was amused.
