Looking at the line-up of speakers at the (Democratic National) Convention, I have developed the 7-11 challenge: I will quit making fun of, for example, Dennis Kucinich, if he can prove he can run a 7-11 properly for 8 hours. We'll even let him have an hour or so of preparation before we open up. Within 8 hours, the money will be gone, the store will be empty, and he'll be explaining how three 11-year olds came in and asked for the money and he gave it to them.
