pink things

My housemate and I were going down to the carpark to move her stuff when suddenly I noticed something pink on the bonnet of my car.

Alas. It was a pink thong.

There was some debate as to whether I should use something to flick it off or just drive and hope the wind blows it off. We decided to leave it on.

Then she walks over to the other side (passenger side) and starts laughing.

The other part of the lingerie outfit has been found, hanging from my passenger seat mirror!

Now we're just curious as to 1. who's it is, 2. how it got there and 3. is anyone going to claim it back?
