Have spare time on your hands at work? Surfing the web aimlessley?
There is a way you can use that time to make a few extra bucks. The site is Amazon Mechanical Turk. Very simply, companies on there will pay you to do a ton of "micro-tasks" - viewing websites, surveys, etc. They aren't offering huge dollar amounts, but you should be able to make at least 5 bucks for an hour of effort. If you are using that time to daydream anyway - this might be useful.
