Go on, you're kidding me, right? Where did you get your PC, did you find it on a beach? Well, I think I've figured out what's wrong with you - you're weird. Not only do you go around sniffing office equipment, but you think it's okay for a computer to smell of tuna. Actually, it occurs to me that this could be symptomatic of a fascinating, extremely rare and possibly quite lucrative condition. I want you to be completely honest here - do you find yourself unusually attracted to electrical equipment?
