Charlie, it squeezes out the top. Up, not out and 'kablooie'. I know you're way older and much more geezerish than I, but did you grow up with milk boxes and milk men? I can remember the stuff freezing!

Freezing milk de-homogenizes it. It wasn't homogenized in the first place, so it didn't matter much. We'd just bring it in and let it thaw somewhere drip-proof. Neighbors used to use the milk box to drop stuff off.

Do you remember (in the US) when your telephone number's first 2 digits were letters? When telling someone your phone number, you usually didn't say the letters, but a word containing the letters. Our letters were FR and the word was Franklin.

Remember when there was no such thing as a zip code?
