I was sitting in line on the onramp this morning, whe I noticed that out of the 5 cars in front of me, 4 had something dangling from the rear-view mirror.  So as I was driving to work, I started paying attention to other cars' mirrors.  I would estimate that maybe 20% of the cars I shared the road with between 7:30 and 8:00 this morning had something hanging from the mirror.

So here are my questions to you: If you own a motor vehicle (street-legal and with more than 3 wheels), do you have something hanging from the rear-view mirror?  What is it?  And why is it there?

(I currently have the site token from Cynaguan Investiture hanging from mine, but usually have nothing there.  And it's there because I needed someplace to put it at the time, and have just been too lazy to remove it.)
