To me this expression reminds me of a Spanish children's song that we sang the school children many years ago: my ass, my ass / it hurts his head / and the doctor sends him / a beanie thick... My ass, my ass you hurt ears / and the doctor sends him / syrup of cherries... My ass, my ass / it hurts your throat / and the doctor sends him / a scarf white /... My ass, my ass / it hurts the heart / and the doctor sends him / droplets of lemon...
