cwh_hobo is a Textpattern plugin that will display a random hobo name from John Hodgeman's list of 700 hobo names taken from his book The Areas of my Expertise (more information here). Once installed, you use it by simply placing the follwing in any article, page, or form within Textpattern:
This will produce a random hobo name, and number, like so:
#171: Twink the Reading-Room Snoozer
<txp:cwh_hobo wraptag="p" class="hobo" />
which would produce:
<p class="hobo">#171: Twink the Reading-Room Snoozer</p>
Pretty neat, eh? You can download this plugin below.
