- according to the Transactions of the Banffshire Field Club (1887):
A man who rode a piebald horse was believed to have the privilege of prescribing for whooping cough. Whatever remedy he recommended was sure to be effectual. One such rider I have heard of who seems to have been a rather ill-conditioned individual, for when assailed with the usual formula - "Man on the piet horse fat's guid for the kinkhost?" he used to snappishly reply "butter an' bear caff"
[Man on the piebald horse what's good for whooping-cough? … Butter and barley chaff].
