here's a sure-fire hit at the office. next time you're at starbucks, get a handful of gift cards. you don't have to pay for the cards themselves as they are worthless unless you load funds on them at the point of sale.

so you have your handful of empty starbucks cards. peel off the little sticker. next, wrap each one in a nice little gift card envelope and place them on each of your co-workers' desks with a note that says "just a little something for all you do".

then, go on vacation for two weeks and laugh the whole time while you think about your co-workers skipping into starbucks, ordering a $4 cup of caffeine, then discovering that there are no funds on the card.

hee-haw-larious!
