Frum

A Reform Jew goes to his rabbi, very depressed.

"My son," he explains, "has become very Orthodox. He goes full time to a yeshiva, and he claims that everything in our house is treif, so he can never eat with us. And worst of all, he's influenced our daughter. She's left home to go study at some super-Orthodox seminary for women."

"And what about your younger son?" the rabbi asks. "The one who was at Stanford."

"The worst case of all." the man answers. "He got hooked up with some Chasidim, and he now lives at a yeshiva in Israel."

"Hmm." the rabbi reflects. "Have you thought of checking your m'zuzoth?"
