An English doctor is being shown around a Scottish hospital.
He is shown into a ward with a number of patients who show no obvious signs of injury.
He goes to examine the first patient he sees, and the man proclaims:

"Fair fa' yer honest, sonsie face,
Great chieftain o' the puddin' race!"

The English doctor, somewhat taken aback, goes to the next patient, and immediately the patient launches into:

"Some hae meat and canna eat,
And some wad eat that want it."

This continues with the next patient:

"Wee sleekit cow'rin tim'rous beastie,
O what a panic's in thy breastie!"

"Well," the English doctor mutters to his Scottish colleague, "I see you saved the psychiatric ward for the last."

"Ach no," the Scottish doctor corrected him, "this is the serious Burns unit."
