So, a Jewish boy is about to go off to college to study accounting in order to manage the books for his father’s business. Before he goes, his father tells him, “Listen. I know that we aren’t very religious, but promise me one thing. Promise me that you won’t marry a shiksa.” The son is taken aback but sees that his father is serious and so he gives him his word that he won’t.
A few years into college, he meets a very nice non-Jewish girl and they fall in love. He tells her that he can’t marry her because he promised his dad he wouldn’t marry a non-Jewish girl.
She thinks about this, and decides she loves the son so much that she’ll convert for him. She studies Judaism for a year and converts. They get married and move back near his father house.
A few months after they move back, the father comes to the son and tells him that he wants to get together that Saturday Morning in order to balance the books. Saturday Morning comes, and the son doesn’t show up. He calls the son and gets no answer. Finally, worried about his son, he drives over to his sons house and frantically knocks on the door.
The son calmly answers the door and the father is furious! He starts yelling, “Where were you?!? I’ve been worried half to death!”
The son says, “Listen, I’m sorry, but my wife told me that I’m not allowed to use the phone or balance the books on Saturday. She wouldn’t let me come over.”
At this, the father finally snaps, “I TOLD YOU NOT TO MARRY A SHIKSA!!!!”
