What did they tell whatsherface when Shane got back without Otis? Did she just assume he was there or did they lie about his whereabouts? Something about that part didn't ring true. And speaking of Shane cutting his hair, all I could think of is how he was wasting water by leaving the shower running.
By the way, I saw Zombieland
the other night and loved it. A great zombie apocalypse movie with some good humor mixed in. Check it out if you haven't already.
