CNN has a Q and A up with an editor who compiled a book of rejection letters. In it, he says his favorite rejection letter is from a student who applied to Princeton's "Law School", only to be told that Princeton didn't have a law school.
So, its all very innoculous, but if you look at the pictures (#7), you actually get to see the rejection letter. The address? 1805 Washtenaw, Ann Arbor, MI. The guy was a Michigan alum.
He did get into Harvard Law though, so the story isn't all bad.
