Haha okay funny story time

I, (yet again, in math class) heard the teacher talking about random algorithms and theorums for later problems and whatnot. Anyway, i was doodling after finishing some stuff and i heard her say "this is marked with an R and the other an L, it must be rationed in half accordingly" (and so on,) .. I almost broke my chair in rocking it back and forth until everyone got quiet and started staring and i just whispered, "....which one's the glassesed half and which ones the tall half?"
