From the comment thread on the Air vents are for air post:

I am an Air Conditioning Duct and I find this entire conversation incredibly ignorant and offensive.

On the rare occasions that I do see my Community represented on screen, it is invariably unrealistic and below industry standard. All the Air Conditioning Ducts of my acquaintance are spotlessly clean, weight-of-a-grown-man supporting structures. However we cannot deflect bullets.

Someday the true poetry of our lives and history will be told.

Despite the occasional a-hole, I have the best commenters ever.
