This woman made some great use out of a fake ID that was all too real.

We don't know the entire backstory here, but it is pretty self-explanatory when looking at this photo.

It says:

Found this on the floor of a bar about a year ago, hope you don't mind I used it for awhile. But -- now I'm 21 so you can have it back! Thanks"

Never has someone been so deceitful and so honest all at once. It was a pretty smart move by the person -- and we're assuming it was a woman -- who found the ID. Scores of youngsters on the doorstep of 21 have gone the fake ID route, so why bother paying when you can try to use one that's real.

Of course, the woman who lost the ID is probably not that pleased. When they say you should pay it forward, we're pretty sure they're not talking about with your current license.
