The Scots can't look at a foodstuff without wondering if it could use more batter and/or lard. What other nation on earth would deep fry a poor defenceless pizza?
They're absolutely disgusting and unfortunately quite real (unlike the old deep fried mars bar myth). The late, great Pete McCarthy used to do an absolutely splendid comedy routine about them.
It is a major health problem, there's no doubt about it though.
When I was in hospital the second time, on Xmas day, they brought in a diabetic guy with severe mobility problems and put him in the bed next to me. But the 27th I was ready to smother him. Anyway, he always had 2 bottles of Irn Bru and a box of Roses. Every day. Then complained that it was his genes.

ETA: Our American cousins will be wondering who the hell would deep fry a pizza, what's a Mars bar, and is Irn Bru medicinal? Welcome to Scotland, lads....
