CSI: Crime Scene Investigation, Season 9

Doc Robbins:
(upon seeing Riley shine a UV light over her teeth) Well, I always thought it was cool that teeth fluoresced but veneers didn't. So, how'd you get it?

Riley:
Somebody bet me that I couldn't jump into a lake with a rope swing in my mouth.

Doc Robbins:
And that pulled the teeth out?

Riley:
No, but it sure did hurt my neck. On my way home I hit a fire hydrant.

Doc Robbins:
And you bumped the steering wheel with your mouth?

Riley:
No, I was on my bike at the time. I flew over the handle bars and hit the cross bar of a chain link fence.

Doc Robbins:
With your mouth?

Riley:
My shoulder, broke my clavicle.

Doc Robbins:
So then how'd you lose the teeth?

Riley:
(points to each tooth) This one was a root canal. This one a post and a crown. And this one... I uh, I was in college, I woke up one morning and it was gone. I don't know what happened to it.
