Wriggle out of this, earthworms just about cut the mustard

After a fine dinner at our home last week, our guest (and chef for the evening) was (figuratively) in full flight and turned to the squirmy subject of earthworms.

This, I should explain, was after, rather than before or during, the meal.

I was surprised to learn arcane facts about these useful creatures, present in perhaps thousands in our garden.
