BS”D
Not original:
Jack Schwartz, a none too frum Jew, ended up in the mental hospital. Since he wanted to be excused from some of the more meaningless therapy once a week and get better food, he told psychiatrists he was indeed “Orthodox”.
All went well for a while, and he was happy with his kosher food and his excused absence from basket weaving on Shabbos.
However, one Saturday morning, his doctor came in and saw him smoking on Shabbos. He threatened to cancel the kosher food and excused absences because Schwartz was so clearly a fake.
Schwartz told the Jewish doctor: “What do you mean? Of course I can smoke on Shabbos! I’m meshugge, remember!?”
