Who was orky duck?

"Orky Duck, orky duck, broke me leg an' I can't get up"

My mum used to say it, no idea where it's from.

Shes a Lancashire lass, if that helps.

I saw someone with a limp today and it popped into my head, so I searched a few spellings and came up empty before trying this one. I only found one reference which gave no origin, just the line at the top of this comment
