I'm really proud of these tricky little rhymes.

The Riddlemonger's Gift also has a primer for using riddles in your ttrpgs, so it makes a great daily puzzler and a GM's companion. I think you will like it very much.
Here are a couple of my favorite riddles from it:
Riddle No. 12
Many serpents in a bed,
Coiled up until you're fed,
Waiting 'neath their blanket red,
Gentle snow upon their head.
Riddle No. 29
Two generals face, like duelists apace,
Scoring up to settle a difference.
Three soldiers each, within hand's reach,
Echoes of objects of innocence.
The chant counts three, soldiers go free,
The victor is crowned by coincidence.
