Quote from Jerome in Everybody Hates Math
Chris: You think I could get an algebra tutor? Rochelle: An algebra tutor? In Bed-Stuy? [fantasy: Jerome is holding a whiteboard on the street:] Jerome: Now, there are six units and 12 tenants in this building. If "X" equals the number of units with televisions, and "Y" equals the people who are at work right now, how many TVs can we steal, hmm?
