It may have seemed like a simple undertaking when he started, but little did artist and curator Ben Sisto know that to answer the question, "Who let the dogs out?"—one of the catchiest and most recognizable hooks in music—he'd have to travel across the world. From cheerleaders to feminist musicians to music execs, many claim to have asked the question first. Sisto has made a part-time living out of telling the story of his search to live audiences, and he has one big conclusion to share: We may never know who, who, who, who, who let the dogs out. And actually, it's not that important. The lesson Sisto draws from his wild eight-year-long adventure is that all creation relies on a shared pool of ideas. We may never answer the question, but asking it is all the fun. Aisha Jamal
