There is a story about a Scotsman whose daughter was being married and, as the bride and groom were about to leave the house, Sandy insisted that they should leave by the back door instead of the front.

“Whist, Sandy,” whispered his wife, “are ye clean daffy?”

“Hush, woman,” he replied, “if there should be any rice throwin', I thocht it would be verra verra nice for the chickens.”
