Gridlock on the Hill
Two bulls on the Hill, in a bind,
Got stuck in an hourglass, you’ll find.
The gears grind to a halt,
As sand times their assault,
Leaving progress way behind.

This limerick uses a humorous image of the donkey and elephant stuck together to represent the way political gridlock can stall progress.
The hourglass emphasizes the idea of wasted time and inefficiency.
