Another question I have is why are sandwiches called a 'piece'? As in my daughter in law will ask the grandchildren if they want a piece?
This may help:
I'm a skyscraper wean, I live on the nineteenth flair,
But I'm no gaun oot to play any mair,
Since we moved tae Castlemilk, I'm wasting away,
'Cause I'm getting one less meal every day.
O ye cannae fling pieces oot a twenty-story flat,
Seven-hundred hungry weans will testify tae that,
If it's butter, cheese or jeely, if the breid is plain or pan,
The odds against it reaching earth are ninety-nine tae wan.
On the first day my maw flung me out a dod o' Hovis broon.
It came skyting oot the windae and went up insteid o' doon,
But every twenty-seven hours it comes back into sight,
'Cause my piece went into orbit and became a satellite.
One the next day my maw flung me oot a piece once again.
It went and hit the pilot in a fast, low-flying plane.
He scraped it aff his goggles, shouting through the intercom:
`The Clydeside Reds have got me wi' a breid-and-jeely bomb!'
