But, Joe, CORK horse makes sense..cock horse doesn't!! cork is a type of wood. Just the stuff to make a rocking horse out of. What sort of horse could one make of..cock??

This rhyme originated in England, now, in both England and Maine, the letter "r" is silent except when appearing as the first letter of a word.

I must admit that we do have an unusual way of speaking, but, By the Jesus chummy, we can spell!! LOL
