We've seen plenty of stunts being pulled between fast food giants - but not one as blatant as this.
Wendy's has released a five-track rap mixtape called We Beefin? that takes aim at its biggest competitors, McDonald's and Burger King.
Spoiler alert: it's actually quite good. Over the weekend, the mixtape, which features an unnamed female MC, hit No. 3 on the iTunes hip-hop charts.
With song titles like Clownin and Rest in Grease, We Beefin? includes lyrics that directly attack McDonald's, like: "You No. 1? That's a joke / Why your ice cream machine always broke? / Why your drive-thru always slow / Why your innovation can't grow."
