Dr. Mindstein staggers into the room, carrying what appears to be a giant ear and attached part of the head. He puts the model down on the table next to the lectern, adjusts his glasses, clears his throat a few times, and says, “I’m all ears!”

He pauses, perhaps expecting someone to laugh, but, as often happens with his attempts at jokes, there’s no response from the class.” “Did everyvon hear me?” he asks, cupping his right hand around his right ear and leaning toward the class. “I said, ‘I’m all ears.’”
