(Ed Johnson-Ott, Nuvo) Not long ago, John Waters acted out an airplane crash with a room full of first graders. The kids loved it. It was the same presentation he gives at prisons. Waters states he is proud of the fact that his work has no redeeming social value. “Strive for art in reverse,” he once said. William S. Burroughs dubbed him “The Pope of Trash.” With his unworldly smile, coupled with a pencil-thin mustache, he looks like a character out of film noir or the stereotype of a child molester.

Working out of his beloved hometown of Baltimore, Waters has shocked and entertained audiences since the ’60s with films ranging from Pink Flamingos and Female Trouble to Hairspray and Serial Mom. He also writes books, creates wonderful music compilation albums and is a sought-after speaker. This Filthy World, his one-man show, comes to Madame Walker Theatre, Saturday at 7 p.m. Waters revises the show on a regular basis, but it’s safe to assume he will talk about his films, his influences, his fascination with true crime and his encounters with the famous and infamous. Expect tales of scandal and debauchery, delivered with impeccable comic timing. There will be a Q&A session as well. You’d be crazy not to attend.
