The Russo Bros on The Empire Podcast
Here’s the podcast, the Clintasha quote is on minute 28 (thanks to distelhawk for finding it!) and apparently there’s even more awesome stuff in it, but honestly, I’m too tired today for more than an hour of podcast.

HAWKEYE. EVERYWHERE. ON MY DASH. EVERYWHERE. HAWKEYE.
