Preston’s expression here is decidedly serious because people are always saying how humorous my work is– even when I’m not tying to make it funny. So yeah– Preston is SOMBER and CONTEMPLATIVE here! Imagine him thinking about a man he shot last week or something.
Oh– but I guess he wouldn’t he wanking his dick while thinking about heinous crimes he committed. Oh well, whatever– it’s just NOT supposed to be comical.
