Question for the group: Has Weird Al Yankovic ever disappointed? Since the 1980s, heâ€™s consistently tapped right into the zeitgeist, found the catchiest song out there, and turned out a pitch-perfect parody, complete with accompanying video. Itâ€™s uncanny. His latest bit of wizardry is â€œTacky,â€ a spoof on Pharrell Williamsâ€™ â€œHappyâ€ that celebrates all manner of uncouth behavior. (Sample lyric: â€œI would live-tweet a funeral, take selfies with the deceased.â€) The accompanying videoâ€”the first of the eight heâ€™ll beÂ releasing over the next eight daysÂ from his new albumMandatory Funâ€”has star cameos from Aisha Tyler, Margaret Cho, Eric Stonestreet, Kristen Schaal, and a twerking Jack Black.
