The 24 hour challenge

This should be tricky. But here's the idea first. You have to come up with a story in a day's time. I'll give you the theme or the opening line to a story. And you post your entry in the next 24 hours. I'll try to pose a new challenge every other day. And the most profilic and the most creative writer will be judged winner at the end of the month. A couple things to bear in mind. Please keep your stories short and please post them in the comment box. All clear? Good, we'll get rolling in the next few days.
