This girl from financial department pissed me off so badly I took 15 minutes of my private time to slightly modify CSS and JS for her user in our intranet panel, made everything pink and blue, animate all the buttons to randomly barrel roll and made the mouse cursor explode colourful star particles with each click.

She *liked* it, said it was *sweet* and *apologized* for being an ass. Robbed me of all the satisfaction. :(
