While curious whether or not a page existed for PDEng on Wikipedia – which there isn’t by the way, I noticed that the history of the PDEng disambiguation page had some pretty funny comments about the course.  Here’s what I found:

Professional Development for Engineers, a program at the University of Waterloo,

• considered almost unanimously as the most useless, frustrating course ever conceived.
• that takes up all your time on co-op term and does not actually develop professional skills.
• that sucks out all of your happiness and tortures your soul.
• designed to ruin your life.

The third one is my favourite.
