You already know how to be deadly, but you may know some folks who need some help. Well, who better to teach us than that darling of deadly Donny Dumphy? A variety Christmas Show at Club One is in the works featuring The Wolf Pack, Keep Six, The Newfoundlander Vs. crowd (of YouTube fame), DJ Sina, Dave Whitty and Gazeebow Unit (of Philly’s fame). It’s also the premiere of Donny’s newest short film, called, you guessed it, “How To Be Deadly.” It is sure to be a night of dirty yuletide hilarity. Advanced tickets are $15 at Fred’s, Ballistic, and Mary Jane’s or $20 at the door.
