Anyone Use Two Dollar Bills Anymore?

When you're broke like I am, you'll start to search around for any spare change for the soda machine, or the vending machine. I just happen to come across, don't ask me how, two $2 dollar bills.

Now, I'm sure at one point, maybe they were as common as the $1 dollar bill, but a small part of me thought, "Wait a minute! This could be worth a lot of money." Guess again. Most $2 dollar bills are still worth, you guessed it, two bucks.

What stinks is I can't even use them in the soda machine. It says very clearly, $1,$5, or $10. Anyone have change for four bucks?
