Minister & a lawyer

A minister and lawyer were chatting at a party.

"What do you do if you make a mistake on a case?" the minister asked.

"Try to fix it if it's big; ignore it if it's insignificant," replied the lawyer. "What do you do?"

The minister replied "Oh, more or less the same. Let me give you an example. The other day I meant to say 'the devil is the father of liars,' but instead I said 'the devil is the father of lawyers,' so I let it go."
