Bruno Mars and Mark Ronson’s 2014 Grammy-winning hit “Uptown Funk” will be featured in a new advertising campaign for Skippy peanut butter called “Be Smooth Like Skippy.” The song, of course, contains the line “smoother than a fresh jar of Skippy.” “Associating an iconic brand like Skippy peanut butter with the iconic, Grammy-winning song ‘Uptown Funk’ was very important to us,” brand manager Jennesa Kinscher said in a statement. “The song does an incredible job amplifying the spot and harnessing the ‘be smooth like Skippy’ discussion that’s already happening in pop culture around the world.”
