This is widely used by International Baccalaureate students in the United States. To "pull an Anthony Leem" is to skip a class in school in order to do work for another class. This also includes asking teachers to skip their class in order to take a test or make up an assignment from other classes missed. Usually when one pulls an Anthony Leem, it keeps going until you're completely screwed.
"Dude, tomorrow I'm going to pull an Anthony Leem; I'm skipping Math to write my History paper, then I'll give the paper to a friend to turn in so I can skip history to do my science lab write up."
