nuh - uh

So my sister calls me and says, "I have seen the face of God."
"Huh?"
"Yes, after all these years, I know what God looks like."
"... and? You gonna tell me?"
"He looks like an old black woman with long gray hair."
(silence)
"Y'ou see, there I was in traffic and I look over and saw a car, and on the front licence plate, it said, 'God is My Co-Pilot' and, well, there he was sitting in the passenger seat."
