Super def rhymes aside, the greatest thing about the late Adam Yauch was his ability to somehow balance earnest activism with heaping doses of wacky-ass bullshit. Sure, he founded a non-profit dedicated to the liberation of Tibet, but he also interrupted R.E.M.’s acceptance speech at the 1994 MTV Music Video Awards dressed in lederhosen and a fake beard so he could angrily declare that George Lucas had ripped him off. Who else could pull that off but one of the Beastie Boys? Nay, the toughest Beastie Boy? Adios, Nathanial Hörnblowér. We’ll miss you dearly.
