How Tired Am I?

So tired that when I was at the hardware store tonight waiting for the credit card swiper to bring up the signature page, I started randomly singing the "doo doo doo dee doo dee doo doo do" part of The Hustle...out loud.

The clerk noticed, and called me on it. I told him it was either that, or The Girl From Ipanema. I think he thought I was insane.

If he did, he would not have been wrong.
