Let’s have a thread of favourite sayings/phrases. Any dialect, any language, any age. Just tell us what it means. One of mine:

“It’s dark over Albert’s Mother’s.”

Referring to gloomy/bad weather in the distance. Heard it in NW UK. Apparently often “Bill’s mother’s” elsewhere.

“How big’s a small dog?”

Variant of ‘How long is a piece of string?’
