I just noticed while rereading that Oscar was squeezing so hard his sandwich that he left handprints. Just how much did he wanted his sandwich? Poor Oscar. And @Arexty, no it's important. The Creepies' physics is already a goner but what about the sandwich physics?
Oscar deserves better in life than to be the punchline. He lost his hair so he should be invincible, yet holds back his true strength every day. He is the TRUE HERO.
Flora started out pretty level headed but is turning into an incoherent oblivious dingbat as the series progresses. I suspect this is for the sole purpose of denying her the hasubando that is Oscar.
