The fact that he was african-american -- no, I just knew it wasn't his car, period. Does race figure in at all? No. You would have jumped in no matter what? Yeah.

All right, wait. Let me see. Okay, thanks. You didn't see twhose car it was, did you? No, I didn't. And off kristin goes. Can you actually do me a favor? Would you mind helping me lift this? He gets up but then seems to have a bad feeling about this. Wasn't there a dude in the car over here before? Yeah. Like on the phone with somebody talking about golfing and tough like that. He makes it clear if she's going to steal those clubs, she'll have to carry them herself. Can you -- are you keys in the car or something. Overhearing it all is this woman. Is this your car? No, not exactly. I'm okay, though. It's a long story. She has her suspicions but says nothing more. Oh, yeah, thank you. At least sheryl martin was able to snap a picture. You took a picture. I just take pictures of people. I could tell something was not right. Did it look like a thief. No, someone I would go out with on a saturday night.
