I've done this over at the NCIS spot and it got a pretty good response, so I figured I would do it here as well.
All you need to know is that:

^- Answers the question.
<- Tells what you're doing.
v- Question.

Example: Do you like the idea of Tiva?

^ Of course.
< Watching TV.
v Favorite Tiva moment?

Even though we're on the Tiva spot, the questions asked don't have to be about Tony and Ziva. Feel free to ask whatever you want.
