Me: (looks at what are, by Cambridge standards, two adorable rats)
Harvard Student 2: I've never seen rabbits with ears that short before.
Harvard Student 1: Or such long tails.
Harvard Student 2: I'm going to look them up on Wikipedia.
Sadly, my bus was coming, and I missed what, I'm sure, was their fascinating realization.
