Long time ago, my great-grandfather who was a staunch absolutist and had never tasted alcohol in his life, had some health problems in his very old age and was taken by his daughters to the doctor (he was a widower). The doctor advised, among other things, to give him three tablespoonfuls of cognac three times a day.
The daughters knew that he would not agree to put 'the drink of the devil' in his mouth if he knew what it was. So they mixed the cognac with some fresh cream and put it in a jar, telling him they got it from the pharmacy as prescribed.
Lo and behold, he couldn't get enough of 'the tastiest, most wonderful medicine ever' and they had to hide the jar as the old man kept trying to take more than he was supposed to :P
