The possibilities for rear view mirror hangies are endless and the trend changes almost as fast as which style of women's purse is currently the best.
In my lifetime, I've seen an incredible assortment of popular rear view mirror hanger-things.
Of course, there's the fuzzy dice (timeless), the CD (I think extra popular in the mid 90s), the wad (the cluster of so much stuff you don't know what's in there, popular in the early 90s), the graduation tassel, garter belt (sexy), and the forever favorite tree shaped scented dangly.
So, what do you choose when it comes to the sometimes smelly, sentimental, religious, superstitious, fun or just plain weird dangly rear view mirror hangy things? Let's be smart about this shall we? It's just not wise to hang up and flaunt anything you're going to get pulled over and possibly arrested for, something valuable or something too reflective (most drivers need to see to drive, including you).

• Smelly: There's a scented rearview hanger for every personality from the sweet and cute, to anime, and even half-clad men and women.
  I didn't look for any fully nude ones, but it wouldn't surprise me if they were around.
  
• Sentimental: You can now get picture frames to hang from your rearview.
  Neat.
  Show off your kids or keep that special someone nearby while you're cruising.
  
• Religious: There are more choices for religious hangers than there are churches in the Bible belt.
  No matter what your denomination or by what name you call God, there is, in fact, a dangly mirror hangy to help always keep your deity in your sights.
  You know, in case you need a reminder to not bash the guy's windshield in with a baseball bat after he cut you off.
  
• Superstitious: It just might be good luck to have a dead (or at least seriously unhappy) rabbit's foot hanging from your mirror.
  There are also safe travel charms from around the globe you can slap up there.
  These also make great conversation starters...
  for the next time you have a complete stranger in your car?
• Fun: You could hang so many trinkets and gizmos from your rearview, why not have some fun with it? What better way to pass time in stop and go traffic than blowing bubbles out your window?
• Weird: My nominee to the currently popular most weird dangly goes to the blue ball guys.
  I see blue balls swaying from rear views and trailer hitches alike.
  Is there something I'm just not getting, or has the meaning of that term changed? Is it now cool to drive all over the country with blue painted testicles announcing your lack of prowess with the opposite sex?

What do you have hanging in your car? your ride? Personality? Is there something extra unique that I missed and you want to share? I'd love to hear about it and see it.
