I always believed that there were none, but on a rewatch of QI, I learned there are actually two:
- Hurple / hirple: To limp (verb) or a limping gait (noun)
- Curple: A strap under the girth of a horse’s saddle to stop the saddle from kicking forward.

I can finally finish my limerick!
A horse that was wearing a curple,
Found the sting of a wasp made him hirple,
Said the horse, “I don’t mind”
“But I’m starting to find,”
“That the spot of the sting has turned purple!”
