A Scottish Minister
He's being escorted around one of the wards, goes up to a patient who immediately launches into a rendition of "Wee cowerin' timourous beastie". The minister, not being able to get a word in, goes to the next bed where the patient launches into "You take the high road and I'll take the low road and I'll be in Scotland afore ye!"
The minister, now rather troubled goes to the next bed and gets assailed with "On the bonnie banks of loch lomond" followed by "Get down South you Sassenachs!"
Finally the whole ward resounds to "Wahay the Scots and Bonnie Prince Charlie and Rabbie the Baird and the Lord of the Isles!"
The minister looks at the Doctor and asks "Why are they all spouting Scottish poetry and the like? Is this the mental wing?"
"No," says the Doc - "this is the Serious Burns Unit!"
