Good Catholic Joke

Four mothers having lunch.
Mother 1: My son is a priest. When he enters the church, everyone says, Good morning Father. (And she's very proud)
Mother 2: My son is a bishop; everyone says, Good morning Your Excellency. (And she's very very proud)
Mother 3: My son is a cardinal; everyone says, Good morning Your Eminence. (And she's extremely proud).
All 3 look at Mother 4 and see what she has to say.
Mother 4: Oh, my son is not a priest. He's just a layman. And he's 350 pounds & 7 foot 6. And when he enters the church, everyone says, OH MY GOD!!!
