Whatever you do, don't try to be a clown! One of the first oral reviews I did in my quest for the badge was also my worst one ever. Towards the end of the interview, they asked me if I had any questions for the board. I thought I had developed good rapport with all of the members of the board, so I thought I would try to inject some humor into the interview. One of my standard questions was something along the lines of the "what type of calls can I expect to see a lot of working here."
Some important information here - this interview was for the Wilmington, OH police department. Yep, Wilmington, as in the Kehough Brothers Shootout (most everyone has seen the dashcam video of this).
So I ask, "Other than the occasional Kehough brother driving through town, what other types of calls can I expect to see here?" They room became very, very quiet. I was the only one smiling. One person answered my question in very short sentences. And then the interview was over.
Strangely enough, I never heard from them again.
I also never made a joke in an interview again.

The "Pick an aswer and stick with it" crowd has the right idea.
