How

How does a blind person know when to stop wiping there butt?

heightened sense of smell?

One of my buddies answer is.."when the dog barks"
Anyone else got an opinion on this..Seen a blind guy walking down the street the other day and i was going to pull over and ask him ,but the old lady threw a fit told me no nookie if i did.
