Perhaps he is like this all day, just try to picture it.
He wakes up next to Wu at 7am, realizes he is married to her and then this face snaps into place. After that he's stuck the entire day with that face. Brushing teeth, showering, trying to eat cereal, driving to work, doing what ever he does for work, coffee break at the water cooler, eating spaghetti for lunch at the Italian food truck, driving back home, arriving before Brianna made it out of bed... actually that could make for a funny skit.
