The story behind HoboJacket, in which the author spends most of his time discussing how he built the site and ends with a comparison to Mark Zuckerberg (note to kid: He went to, um, Harvard). Among the valuable life lessons he learned from making bums/Caltech the butt of his joke:
People like to mess with you. The forms on the page are only capable of submitting integers to the database server (ie. every state and university has a numerical id; all data transmission is conducted by passing around those ids and some other datum.). I took a look at some of the server log files. People were sending post requests to donate "balls balls balls" on behalf of "dicksuniversity". I'm glad I took the effort to sanitize inputs or else the database would have been wiped several times already.
Oh, yes, thank goodness for sanitized inputs!
