Jeremy warned his son against marrying a 'shiksa.'

The son replied, "But she's converting to Judaism."

"It doesn't matter," Jeremy said, "a shiksa will cause problems."

After the wedding, Jeremy called the son, who was in business with him, and asked him why he was not at work.

"It's Shabbos," the son replied.

Jeremy was surprised and said, "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," Jeremy said, "I told you marrying a shiksa would cause problems."
