It’s often said you can’t be true to your art without offending your mother. John Fugelsang, comedian, actor, ex-TV host and jack-of-all stages, whose one-man show All the Wrong Reasons is premiering at the New York Theatre Workshop, has been there and then some. Fugelsang’s autobiographical show rides on the therapy-inducing teaser that his mother, a former nun stationed in Africa and father, an ex-Franciscan monk from Brooklyn, left their first spouse (God, for both) to marry each other and spawn his talented second coming. Of course, this was the story he was never supposed to tell.
