A Jewish businessman warned his son against marrying a non-Jew.
The son replied, "But she's converting to Judaism."
"It doesn't matter," the old man said. "A shiksa will cause problems." The son persisted.
After the wedding, the father called the son, who was in business with him, and asked him why he was not at work. "It's Shabbos," the son replied.The father was surprised: "But we always work on Saturday. It's our busiest day."
"I won't work anymore on Saturday," the son insisted, "because my wife wants us to go to shul on Shabbos."
"See," the father said. "I told you marrying a non-Jew would cause problems."
