From (pretending not to hear what was said). The original saying contained instead of  and referred to animals when they did not move even the tuft of hair at the end of their ears to follow the owner’s orders. Later, as the phrase was used figuratively and the original image was forgotten, the two words were switched because of their similar sound.
