Last year I had my 3GS shipped to my workplace and Fed-Ex for some reason delivered to a different area of the business then usual so my boss received the package. He thought it would be funny to open my 3GS and slip his iPhone 2G in the box. He then neatly repacked the box and I didn't find out until the end of the day that he had been carrying around my new phone in his pocket. Of course hilarity ensued for all involved except me. I secretly was enraged but put on a fake smile as I left work. I remember being so pissed that he had opened the package. You don't mess with another man's electronics! 
I put in a vacation day this year to avoid a repeat.
