Here's mine...

I was driving to a burger place and notice a very cute girl in the car behind me. Coming up to a red light I took the opportunity to watch in my rear-view. She had very thick brown hair, about brastrap length, pulled in a ponytail. When she stopped her car, she took out the ponytail, and pulled it back again. She had turned her mirror to see how it looked, then proceeded to turn her head from side to side to see how it swung behind her. At this point I'm sure I was drooling a little bit. Apparently, it didn't swing well enough, so she took it out, tossed it around a bit, and repeated. I'm not sure how many lights I sat through watching this, but it was definately worth it!
