"Tacky" is a song by American musician "Weird Al" Yankovic from his fourteenth studio album, Mandatory Fun (2014). The song is a parody of the 2013 single "Happy" by Pharrell Williams. The song mocks questionable taste in fashion as well as activities considered gauche. Yankovic recorded the song as one of the last on Mandatory Fun, and received Williams' approval directly, through email. He remarked he was "honored" to have his work spoofed by Yankovic.
