After a year, the son telephones the mother to tell her that he and his wife are expecting a child. The mother is happy for him, but there is still quite a bit of tension in the air.
Nine months later, the son calls the mother again. "Mom," he says, "I just wanted you to know that last night my wife gave birth to a healthy baby boy. I also wanted to tell you that we've talked it over and we have decided to give the boy a Jewish name."
Upon hearing this, the mother is overjoyed. `Oh, son, this is wonderful,` she gushes. "I've been waiting for this moment all my life. You have made me the happiest woman in the world."
"That's great, Mom," replies the son.
"And what," asks the mother, "is the baby's name?" The son proudly replies, "Smoked Whitefish"
