Not really a fired moment because it was a university project.

A colleague of mine decided it'd be nice to set placeholder images to Hitler wearing a hello Kitty Nazi uniform. Oh without telling anyone, of course.

I go into the lab that a couple lecturers share, one of them was interested in the project we were working on and to our surprise the placeholder images pop up. I immediately say sorry, I didn't set that image and the guy looks at me with judging eyes.

Same guy has to take meds daily otherwise he acts up, not sure what it was he had, may have been ADHD, anyways we were staying late and he forgot his meds, and while our client is in the same room this guy starts doing the macarana behind the room separator, while we're supposed to give him a live preview of what we had accomplished in three months of work. Needless to say he didn't see him dancing like a moron but wow :/ learn to control yourself.

Same guy also never commented his code and used the two letter variable principal because it's such a great idea >.> Me and the other guy spent 6 hours rewriting his code, which should have been less time but he wasn't there to help nor was he available to yell.. I mean ask for help.

I hate University group projects....
