More importantly, he sheds new light on what the deal is with his 'stache in his answer to questions about working with the Bored to Death crew:
They give me everything I need to work with comedically, and from a writerly point of view, it's fun to connect the dots and say, "Who is the person behind all of these wild emotional swings?" And it kind of wasn't until I grew a mustache that I figured it out. I think that's true for a lot of men who grow mustaches, about a lot of things. The mustache is an affectation that I grew as a joke, and then just sort of enjoyed, and it allows me to really embrace wholeheartedly the idea of affectedness, and affectations in one's personality. [...] I really think it fits with the kind of derangement that you have to go through when you are confronting your mortality at the age of 40. So I will keep it as long as America will allow me to keep it. [...] So far, people have been very tolerant of it. But I'm not going to get tied down. Maybe I'll shave it off tomorrow, I don't know.
