In the old days in the Scottish highlands it would get extremely cold during the night when the fires in the castles would burn out. The laird o' the castle was posing a question to his wife about how he might get his own head warm. He noticed that his wife's head was extremely warm---possibly due to hot flashes during menopause. Soooooo, he was askeing her, "Caldonia, Caldonia, why is yor big head so hot!!" He was trying to learn her secret.
