NEW YORK (WFAN) — Fair warning: speak ill of MSG host Al Trautwig on Twitter, and he may just track you down.

A New York Islanders fan named Yehuda — and his mother — found that out after this little exchange:

Another new tv career is born. Spelled boron. — Al Trautwig (@AlTrautwig) November 13, 2013

@AlTrautwig Thought it was an autobiographical tweet and you meant Moron. — Yehudah Block (@Blocknesmonster) November 13, 2013

Trautwig apparently then did some sleuthing and called what he thought was Yehuda’s phone number. He reached Yehuda’s mother instead, who informed the MSG host that her son no longer lives stateside. He’s in Israel — and has been for years.
