The whole nine yards?

Question

anyone know where the saying (the whole nine yards) come from

Answer 1

One theory comes from making a suit. the jacket, pants and vest would consumer an entire bolt of fabric, nine yards. So the whole nine yards is everything

Answer 2

during ww2, american fighter-planes carried nine yards of 50 caliber ammo in belts. pilots would tell eachother to shoot all of those nine yards at the enemy.

Answer 3

As I understand the saying "the whole 9 yards" comes from the days when a horse and buggy delivered coal, dirt, and the like, the cart held about 9 yards of the material.  When it was time to deliver, the owner would ask his customer, "Do you want the whole 9 yards?"

  No more horse and cart deliveries but the question stays on.
