Obviously the horses weren't the brains behind the operation. They were used to add physical strength to the effort of... putting Humpty Dumpty... back together... who I definitely remember as an egg but am just now realising was only illustrated that way and never actually referred to as an egg in the text of the rhyme itself...

Anyway they probably pulled carts of equipment or something idk how you put an egg back together. Or a human for that matter.

This is peak comedy right here

"Have you come up with a solution yet?"

"Neighh"

Obviously the knights turned the horses into glue but it didn’t work

I do feel like all the kings men were doing the bulk of the work on that one.

Damn it, Im a horse, not a doctor!!

Yeah, sure, but how does the horsey move?
