Just because something is posted on Wikipedia does not make it public knowledge in the frum world. Most people, presumably, would not spend their time searching the real last name of a comedian. I don’t believe there is any practical purpose to discussing this. If there is ANY shame brought upon this family by this thread, then all those who contribute partake in the aveira. It’s time to end this frivolous discussion.
If you truly want to spend your time being osek bemitzvos, please guide me with a problem I just became aware of, that can affect MANY (I will post, IY’H, on a follow-up thread).
