Did you know that a hobo once ran the US treasury? That, and more, may be learned by reading the excellent book by John Hodgman, The Areas Of My Expertise.
Even though he can't read, Army Don* seemed quite happy when Yum Lass** and I gave him a copy of this very book for Xmas. When he got to the list of 700 Hobo Names, he couldn't help reading the first few out aloud, and we all agreed that the best one (at least on the first page of the list) is All-but-dissertation Tucker Dummychuck. You can see the full list online here, along with pictures of the hoboes submitted by real people.
And as an extra treat for those that can't read or like listening to things, KUOW's The Beat featured a repeat of an interview with John Hodgman. It's fun.
* An anagram of his real name, to protect the innocent.
** Another anagram.
