Lyrical references to Mercedes-Benzes have been a hip-hop mainstay for decades, but most rappers prefer upscale rides like the S-class and G-wagen. The 190e has received scant affection. Two Norwegians have corrected that oversight in mindbendingly awful style. (Video slightly NSFW due to typical wannabe-rapper language.)
I'm inclined to think (read: I really, really, really want to believe) that this is some sort of Lonely Island-grade parody of a metric asston of rap cliches, but there's a disturbing lack of smirk happening here. It's like they actually mean it. Respect just remembered it had to pick up some groceries and left.
