James Ward wasn’t trying to be cute. Yes, he knew he was wearing a cheeky slogan on his back when he started working the other day for the Yale recycling pick-up crew. And Ward, who’s 49, likes the slogan — he thinks it’s clever. But while the slogan may look spray-painted, it actually comes with the shirt, part of the official uniform. Does Ward really want people talking trash to him? Not really, he said. “It’s just a joke.”
