This Is Part II:

Last week one of the guys I work with didn't log off his computer when he left. I decided it was my responsiblity to remind him just how important this is. So I left this as his desktop wallpaper:

Yes I drew that. Yes I had a lot of time on my hands. Yes I also changed his screensaver to read "I love fluffy bunnies!!" in bright pink letters.

Needless to say he doesn't leave his computer logged in when he leaves anymore.
