Little ditty used by the Irish Board of Health (An Bórd Sláinte) and the Irish Food Board (An Bórd Bía) in an advertisement promoting the goodness of milk (late 80s - early 90s). It can oft be heard hummed or slurred drunkenly when anyone mentions calcium, bones or milk as it's a catchy tune:
Dem bones, dem bones need* calcium;
Dem bones, dem bones need* calcium;
Dem bones, dem bones need* calcium;
And dat's* de natural law.
*pause
So Mr. Bones, it seems the population of Ireland has been drunkenly singing your health all these years ;)
