according to Quinion [see link], it's from an 18th century translation of a Spanish playwright; he also includes this verse to demonstrate the meaning:


Teach not thy parent's mother to extract
The embryo juices of the bird by suction.
The good old lady can that feat enact,
Quite irrespective of your kind instruction.
