I found a slot machine called American Original. Everything on it was some combination of reds, whites, blues, stars, and eagles, so I had to play it. I put in $50 and got bonus after bonus, eventually winning up to $105 before cashing out with $90.
It's an added bonus for loving my country!
Update, 7/18/08: Sadly, that luck didn't hold out last night. Maybe a bunch of liberals came to the casino =)
