True fact about me: I am kind of the biggest Pearl Jam fan in the world. Okay, maybe not the biggest, but pretty big. I’ve been to eight of their shows and once made a paper mache trash can with Stone Gossard’s face on it. Whatever. Anyway, the band is celebrating their 20th anniversary — which does not make me feel old in the slightest, nope, definitely not — and lead singer Eddie Vedder stopped by “Late Night with Jimmy Fallon” to sing a funny protest song called “Balls in Your Mouth.” This proves I truly will listen to that man bellow anything.
