What is the origin of the phrase "open mouth, insert foot," and "put your foot in your mouth"?

Question

I know what it means, but when was the phrase first used, by whom, and under what circumstances?

Answer 1

I'm not sure when this phrase started, but you missed one.
"Open mouth, insert foot, chew."

Answer 2

Open Mouth Insert Foot

Answer 3

In the book of Numbers in the Bible it says 'The Lord opened the mouth of the A$$.' I'm sure it didn't take much to insert the foot.

Answer 4

The original phrase was "to put your foot in it," meaning to say or do something inappropriate and embarrassing. A joke based on this phrase was, "Every time he opens his mouth, he puts his foot in it." The intended joke then became unintentionally institutionalized as "to put your foot in your mouth." (Compare the erroneous shortening of Shakespeare's original "paint the lily or gild pure gold" to "gild the lily.")

Answer 5

PUT YOUR FOOT IN YOUR MOUTH - "Irish Parliamentarian Sir Boyle Roche was sort of the 18th century equivalent to (former U.S. Vice President) Dan Quayle. Roche once said, 'Half the lies our opponents tell about me are not true!' Someone with a much firmer grasp of the English language remarked of Roche, 'Every time he opens his mouth, he puts his foot in it,' and a phrase was born."
