[Rain Man]

I dump some off in an IRA before I even see it, which is nice.

For the rest, I have very few bills these days:

Credit card bill, which is usually quite large because I put everything on it (and then pay it off each month)
A couple of utility bills - gas, cable.
A couple of tax bills

That's pretty much it. I always have some cash on me because I can't stand how modern people walk around with no cash, and yet I very seldom use it.
