Let everyone pick his own nose.

Hold your nose to the grindstone

It's not how you pick your nose, it's where you put that booger that counts.

Many a man's nose was broken by his mouth.

If you pick up some paint with your brush and make somebody's nose with it, this is rather ridiculous when you think of it, theoretically or philosophically. It's really absurd to make an image, like a human image, with paint, today.

Sorry to be crude but we did not pick these prices out of our nose.
