Hair pieces at work, really?!

Ok. Where do I start. Lets begin with the 45-plus year-old woman in my meeting earlier with the massive fake hair clipped to her ponytail. I do have to give her credit for how closely the color matched that of her natural hair (a soft brown), but the clip itself was falling halfway out and looked completely and utterly ridiculous for someone sitting in a corporate office at noon.

Have you seen any outrageous hair pieces on your co-workers? Appropriate or not?
