The loaf of bread I bought yesterday is labeled "Extra Sourdough Bread." Does this mean that you can buy it only if you already have some bread and need some extra? Or does this mean that they had a lot of leftovers at the factory? (OK, I'm guessing that bread isn't really made in a factory, but it's funnier than "bakery.")
So how would one correctly point out that the sourdough bread is extra sour? It would have to be "extra-sour sourdough bread," neh? I'm not sure that "extra-sour bread" would convince anyone that it was tasty, plus what happened to the dough?
OK, back to real work--
