Who cares?

PEMA: Lisa, do you know when--? How do you--? Do you say "whom do you love?" or "who do you love?"

LISA: Whom cares, Pema?

(Then Lisa looked it up, because she is someone WHO cares after all.)

he = who
him = whom

(Repeat that a few times and see if you can say it without smiling. Or feeling sexy like an owl.)
