he wrote this fabulous op-ed piece in the new york times about dogs. i think he's pretty amazing, and now that i know he walks his dog twice a day in prospect park, i want to go hang out in booklyn and (nicely) stalk him.
he also narrates this expose of agriprocessors kosher slaughterhouses. you're not going to want to actually watch it, believe me.
he also wrote a couple of really wonderful books.
