Some nice replies here.

Increasingly we are seeing on remodels requirements to follow the NEC and remove wire that is currently unused. I like Oldtimer1's top ten.

Occasionally we get to keep the removed wire and at current prices ranging from .80 to 1.40 a pound, which adds up to extra bucks very quick! On one job our installers got over two grand for the scrap they pulled out! And that was only a portion of what was eventually removed!
