Good luck on getting out of a hole you dug yourself in before they determined that you make a good culprit. Lawyers do love themselves a client that decided they needed a lawyer after talking for hours.

If you are sure you a only a wittiness and have something worthwhile to contribute prepare a statement, give that and nothing more. If they have more questions repeat the process. Once you start a conversation you are betting on how much CSI the officer saw recently and how shady they think you look.
