Matthew Lesko, known to infomercial watchers as “the question mark guy,” stopped by the Tune Inn with family and friends Friday night. Dressed in one of his trademark question-marked jackets, Lesko sat in the front window and graciously waved to the many Pennsylvania Avenue pedestrians who slowed to stare. Lesko, the author of more than 20 books on getting “free money” from government grants, also posed for pics with some enthusiastic Tune Inn patrons.
