Actually You Can Flog A Dead Horse

Teacher: “Okay, this week we’re going to be teaching about animal teeth and how they vary depending on what the animal eats. We’ll be using the various skulls I have so you students can get a hands-on look at the teeth. Each group is going to need the skull of a herbivore, carnivore, and omnivore. I’ll start assigning those now.”

Student: “Cool. Is this one a horse?”

Teacher: “Yes. That one’s Heidi. We had to have her put down about five years ago.”

(It turned out all three of the horse skulls she had were from horses she had actually owned, and she could still recognize which was which. Whenever they died she’d put the head in a tank with some flesh-eating insects and let them clean the skull off. To this day she’s still the coolest teacher I’ve ever had.)
