I was separating the good lettuce from the bad at In-N-Out one day. Gotta make sure we have the best quality product... So anyways, I was thinking to myself, why are they called "heads" of lettuce. Sure, I guess they sorta look like heads. But you don't see people calling grapes, "marbles" of grapes, or some other shit. I mean, why not? They have "ears" of corn, and they sure as hell don't resemble an ear.
