One of my friends at work, who I'm convinced is a nine-year-old trapped in a thirty-year-old's body, was headed out, so he made one last run through the kitchen to see that everything was in order.
As he left though, he grabbed a couple of our sandwich stickers that had fallen onto the counter, and instead of throwing them away, he proceeded to very cautiously place them on the back of our unsuspecting coworker's butt. One on each side.
The sticker looks like this...
Unfortunately, the victim felt him when he came back and tried to add a "2 for $3" to the mix. There's really nothing more hilarious than the inappropriate use of stickers.
