School's a Drag (S02E03)

Geneva starts her new position as a music teacher at the high school, with Mark guiding her around. There's buzz about a new principal who’s notorious for firing staff, and it turns out to be P.J. Moore, Mark's sister's close friend. She immediately expresses her disdain for Mark’s teaching style. Meanwhile, Mark is dismayed to find Driver's Ed on his schedule. When Darnell borrows the Driver's Ed. car without permission and damages a lawn mower, he implicates Mark, leading to potential trouble with the school. To avert disaster, Mark disguises himself as P.J. to meet a man seeking a settlement at a karaoke bar. After successfully getting him to sign, the real P.J. arrives, and Mark scrambles to hide. Eventually, she spots him but recognizes his passion for teaching and decides not to fire him.
