In Australia there is a snack food called Cheezels (I don't know if they exist elsewhere in the world). As a three-year-old, I used to sing the Christmas carol 'Away in a manger' thus:
'Away in a-a manger, no crib for a bed, the little lord Cheezels lay down his sweet head.' Later in the song: 'I love thee, Lord Cheezels, look down from the sky, and stay by my bedside til morning is nigh.' I really did love that lord Cheezels!
