Father Callahan and his friend Rabbi Silverman are sitting down for their weekly breakfast together. Father Callahan orders bacon and eggs, while Rabbi Silverman chows down on lox with bagels.
Father Callahan puts some strips of bacon on Rabbi Silverman's plate. "You should try it," says he, "It's delicious."
"I'll try it," says Rabbi Silverman. He keeps eating his lox and does not touch the bacon strips.
"When are you going to eat the bacon?" asks Father Callahan.
Rabbi Silverman replies, "At your wedding."
