I'm going out with an office buddy to look at it at lunch, I hope it's nothing and just a button that did not get reset. Dammit.

What kind of car? You can take it to the nearest autozone, and they will scan the error codes for free.
Are the temperature and oil pressure ok?
GD is right, a loose fuel cap will trip the light. On newer cars, for emissions, they will pressurize the fuel tank to detect a leak. A loose fuel cap will look like a leak.
