Drinking is like breathing for Amy Schumer. She does it all the time on her show unless it's, like, a graveyard scene or whatever, because it's true to her life. Girl loves the drink. So imagine how hard it must have been for her to not drink for a week before going on the Late Show with David Letterman! (Okay, she cheated a teeny bit).
They also talked about what kind of alcohol Amy likes. All kinds! Red kinds, white kinds, pink kinds, and Scotch kinds. We can toast to that. And so can Dave.
