I found this inside a old business card from
Stateside Locker Club, San Diego, CA:

In a South American mining district Mrs. Brown presented her
husband with a 12 pound baby boy. Mr. Brown was so delighted that he
went to the News office and told that he had found a 12 pound nugget of
gold as good as any to be found in South America. The paper, naturally,
sent a reporter to get particulars. This is what happened:

Reporter–Does Mr. Brown live here?
Mrs.Brown– he does.
Reporter–Is he in?
Mrs.Brown–No he isnt.
Reporter–I understand he found a nugget of gold weighing 12 pounds.
Mrs.Brown–(Seeing the joke) Yes.
Reporter–Can you show me the exact location where it was found?
Mrs.Brown–Im afraid Mr. Brown would object as it is private.
Reporter–Is the hole far from here?
Mrs.Brown–No, it is quite handy.
Reporter–Has Mr. Brown been working the claim long?
Mrs.Brown–Almost ten months.
Reporter–Was Mr. Brown the first to work it?
Mrs.Brown–He thought he was.
Reporter–Was the work difficult?
Mrs.Brown–It was at first but easier after the shaft opened.
Reporter–Is the water plentiful?
Mrs.Brown–Yes, sufficient to carry on the work.
Reporter–Has he gotten to the bottom yet?
Mrs.Brown–No, but quite near it.
Reporter–Do you think there are any more nuggets?
Mrs.Brown–Yes, if the claim is properly worked.
Reporter–Has he worked it since he found the nugget?
Mrs.Brown–No, but I told him it was time to start.
Reporter–Do you help him?
Mrs.Brown–I do my level best.
Reporter–do you think he will sell the claim?
Mrs.Brown–No, he finds too much pleasure in working it himself.
Reporter–Can I see the nugget?
Mrs.Brown–Certainly.

She brought the baby in for inspection. The embarrassed reporter
departed very fast.
