Godlike son

Four Catholic ladies were having coffee. The first said: "My son's a priest. When he walks into a room, everyone calls him 'Father.'"
The second lady said: "My son's a bishop. When he walks into a room, they say, 'Your Grace.'"
The third lady said: "My son's a cardinal. When he walks into a room, they say, 'Your Eminence.'"
The fourth lady sipped her coffee in silence.
"Well?" asked the other three.
Finally she said: "My son is 6 feet 2 inches tall, wealthy, and gorgeous looking. When he walks into a room, people say, 'Oh my God!'"
