At no point in the entire episode, even during the supply run, does Our Hero stop to put on pants.

This made me laugh so hard. Like, he steals a car, plans a road trip and considers paying for junk he takes from the WoS, but is never like, oh hey, maybe I should get dressed?

Maybe once he had his trainers on, he was too lazy to take them off again to get his jeans on and because there was pretty much nobody else around, he was just like, fuck it, no-pants SAturday it is.
