Go Green or Go Home! On March 17th, the streets will be teeming with eagle-eyed sadists who can’t wait to pinch you for disobeying the well-established laws of St. Patrick’s Day. The rules are simple: Wear green, or wake up black and blue the next day. Beat these ne’er-do-wells at their own game by decking yourself out in these wild T-shirts that pull out all the stops: We’re talking leprechauns, four-leaf clovers, pints of beer, rainbows, and unapologetically punny wordplay (ie, “Let’s get ready to stumble,” eh?) These looks are so damn dapper, people will be more than eager to kiss you… whether or not you happen to be Irish.
