Baab is discussing his schoolwork with his mother. The discussion moves on to class exams.
Mrs. Porcupyn: “You need to be prepared for your next Science test. How often are you tested? Are you tested monthly?”
Mrs. Porcupyn: “Quarterly?”
At this point, Porcupyn is all set to endure the latest round of mother-son 20 questions, but Mrs. Porcupyn cuts to the chase.
Mrs. Porcupyn: “OK, how often then?”
Porcupyn –> ROTFL! 😉
