A mysterious man has been showing up at Ted Cruz's campaign events in Iowa with a sign reading "Ted Cruz Likes Nickelback," amusing the hell out of the Internet and generally doing God's work. Everyone knows there's nothing worse than being accused of liking the Canadian band Nickelback (no offense, Nickelback!) except maybe being accused of liking other Canadian band Barenaked Ladies (sorry, Barenaked Ladies!). Especially when you're accused of being a secret Canadian.
