I inherited a half-'finished' system from a former employee... well, I knew she had her quirks, but I gave up trying to 'fix' her code as long as she was around to maintain it... ah, well. Luckily her replacement inherited most of her stuff, but I got this one as it was high-profile (sorta) and I've been around longer. It's a combination Job announcement/application/resume builder package.
I could tell you about the 100+ lines of javascript validation code that never ran (because of a typo in a function that she obvious copied from some javascript site... and never actually called)
I could tell you about the logic flaw that prevented anyone who just created an account from creating a resume - unless you were the first user in the system.
But I think it is best summed up by a single line of CSS - scattered throughout various pages, of course, there was no .css file originally:
.minitext {font-family:Rockwell; font-size:12pt;}
