Song: Rihanna f/ Eminem "Numb" (2012)

At one point, it seemed like the older Em got, the more juvenile he sounded. His butt jokes used to be funny (or, at the very least, were riffs on funnier bits by Tom Green.) But by this point, it seemed like Marshall had a case of "cool dad" syndrome. He captured the words of juvenilia, but none of the irreverent spirit. Pro tip, Em: no grown woman is gonna want to hear about how you're the butt police.
