Sometimes, it is fun and games
Last Friday was our boss' birthday and we came up with our own way of celebrating. We bought about 600 balloons and filled his entire office. Then we covered his windows with 'Happy Birthday' signs, so he wouldn't see the balloons until he opened his door and they all came tumbling out. There are now balloons all over the place and even creeping into the rest of the building. The best part was how truly appreciative he was of our gesture.
