How would you keep a giraffe in a secret underground facility? Think of the space it would need, the food, the mess...

...Oh wait. Magic. We can do that here.

Well, almost. They certainly like getting it on, but only 9% of total giraffe mating is heterosexual, which is another hit to Emily's chances. The rest is 90% male-male and 1% female-female.

And yes, I happen no know an unusual amount about giraffe mating, but I can't guarantee it will be covered in the classwork.
