Amy: Let's just play.
Sheldon: I'll start you off easy. Electric eel, pufferfish, shrimp.
Amy: Hmm. Well, I wouldn't fight the eel, because I know it can generate enough current to kill a horse.
So I'd eat the eel, fight the shrimp, and befriend the pufferfish, because it would be nice to have company on those days I feel bloated.
