I'm good for any part of that time frame. Maybe you should ask the Devil (Weasel?) to pick the final date.

1. He issued challenge.
2. You accepted & set venue. (With great generosity, I might add.)
3. He sets final date.
4. Somebody whomps somebody's butt.
5. I'm embarrassed by my shooting.
6. Somehow, the world keeps turning.
7. Everyone has a good time.
