"Foil" 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 "Royals" by Lorde. The song begins as an ode to the multiple uses of aluminum foil for food storage, but takes a darker turn in its second verse, parodying conspiracy theories, the New World Order, and the Illuminati. The song's music video stars Yankovic as the host of a cooking program, and features cameo appearances from Patton Oswalt, Tom Lennon, and Robert Ben Garant.
