For years it's been an angle air freshener.

When I was a teenager it was my high school graduation tassle. Then I added my college tassle. Ex-girlfriend found one from 1957 and bought it for me. That went in my first car.

For a time it was a red thong. (female. not a guy version thank you)

 

Hahahaha

 

is this for real cuz that'd be awesome!

i have nothing hanging from mine

 

Picked it up an an air show.

I also carry a Roswell Crash Recovery Team ID on the other side of my real work ID that hangs from my belt. And a sign on the warehouse chain link fence that says "restricted area, trespassers will be abducted and probed"

 

I can concur with enzo, I have my 2011 tassel on my rear view as well. It may be illegal but I sure do love to watch it when my subs kick.
