If you'd like to own an amazing - and heartwarming - piece of history, now's your chance. Back in 1986, an 11 year old girl named Lisa entered a walkathon. The proceeds would go to help the homeless. Apparently, Lisa decided to "go big" with her donor list, so she wrote a letter to the leader of the free world asking him to sponsor her efforts. Fortunately, the man in the oval office at the time was a pretty great guy.
