I think it's supposed to say "professor is pissed, as this poor guy..." Pretty sure it's like this:  Professor to fat: why are you always late? Fat to professor: its not like you have to drive 2 hrs Professor to fat: <glaring at her soda> keep coming late I will lower your grade  Moral of the story: Fats are uppity and self-important, and professors are capable of subtle shaming. Nice story but unweildy delivery.
