Comedian Dusty Slay’s on stage persona isn’t a gimmick. He really did grow up in a trailer park in Tennessee and he really did sell pesticides for 10 years. In fact he talks about all the jobs he had before achieving success in the stand-up world in his Netflix special “Working Man”. He’ll also be at The Shubert Theater in Boston on March 14th. Mike Hsu talks about his constant on stage encouragement, giving up cigarettes and performing at The Grand Ole Opry.
