Origins of the phrase "like nobodies business"

Mornin' All,

Just wondering about the origins of this phrase... as far as I can remember its a phrase that avoids you swearing, like "Bloomin' heck" as apposed to "Bleeding Hell", usually said with a pause... i.e.

"Like.... nobodies business"

Searched all over Google and Turbo10 but can't find anything.

Any help appreciated.

Type 'nobody's business' in the Search box and you'll get some results.
