“People who live in glass houses should take out insurance”

“Those who live in glass houses shouldn’t throw stones” (one shouldn’t criticize others when the same criticism can be directed at one’s self) is an old proverb from at least the 17th century. “People who live in glass houses should take out insurance” is a jocular variation.
   
“People who live in glass houses should take out extra insurance” was published in the column “The Melting Pot” by Ema Spencer in The Newark Advocate and American Tribune (Newark, OH) on December 3, 1934.
