Sir Patrick, who plays Professor X in the X-Men films, said he was seeing his GP the next day for a check-up. He said: “While he was down there I said, ‘By the way, my wife and I have had a

little disagreement. I am circumcised, aren’t I?’ "He took a closer look and said, ‘Not! I am Jewish, and definitely know the difference!’” Upon realising he had maybe revealed too much

on the popular chat show, Patrick exclaimed: "Oh no, my grandchildren will be watching this!"
