Stephen's joke

In the run-up to the last British election, Tony Blair was being shown around an Edinburgh hospital by its administrators. Towards the end of his visit, he was shown into a ward of people exhibiting no obvious signs of injury.

He greeted the first patient and the chap replied:
"Fair fa' your honest sonsie face,
Great chieftain e' the puddin' race!
Aboon them a' ye tak your place,
Painch, tripe, or thairm,
Weel are ye Wordy o'a grace,
As lang's my arm."

Tony, somewhat confused, performed his sparkling grin and moved on to the next patient, again greeting him with a smile and hello.

This patient replied:
"Some hae meat, and canna eat,
And some eat that want it,
But we hae meat and we can eat,
And sae the Lord be thankit."

As Tony was led towards the third patient, that patient began rattling off as follows:
"Wee sleekit, cow'rin, tim'rous beastie,
O, what a panic's in thy breastie!
Thou need na start awa sae hasty,
Wi bickering brattle!"

Tony turned to the doctors accompanying him and asked, "Uhmmm, I say, whatsort of ward is this, a psychiatric ward?"
"No," replied one of the doctors, "it's the serious Burns unit."
