Here's a great way to have fun at the office and use supplies to make something you can claim is a useful tool you need at your desk.

Not all offices have clothespins and glue guns available, so you might have to bring in a few things from home (or check with your co-workers, you'd be amazed at what some people keep in their desk.)

How to convince your boss this is not only a productive use of your time, but your grappling hook won't be used to annoy fellow employees, is all up to you.
