Some people just hate fun. Where “Weird Al” is concerned, however, those people are few and hard to find. Not only did last year’s Mandatory Fun top the Billboard 200 chart — the first time for a comedy album to do so since the early ‘60s — those harshest of critics, YouTube commenters, viewed the eight videos he made millions of times, and the responses are almost entirely of the LOL variety. Even when he rewrites controversial club banger “Blurred Lines” to expound in great detail about proper grammar usage, even when he used “Foil” (satirizing Lorde’s “Royals”) to bait Illuminati conspiracy theorists, the commenters just keep on ROTFLing. If ever a man could dictate fun, it’s Supreme Leader Yankovic. May he reign for a thousand years.
