'The phrase "Aunt Sally" is often used to describe a person or organisation at whom it is easy to take a cheap shot.

The phrase originated in the 19th century as a fairground game, in which a doll or moppet was set up, usually taking the form of an old woman, in whose mouth was a pipe. The object of the exercise was that players had a number of balls to throw at the effigy in the hope of dislodging the pipe from its mouth.

By 1898, the game was sufficiently well-known that the expression "Aunt Sally" could be used figuratively to describe someone who was the object of attack, both easy and unwarranted.'

Sort of like the threads at times :)
