A pompous Scottish laird met a farmer one morning, and observed:

‘Well, Sandy, you’re getting very bent. Why don’t you stand up straight,
like me?

‘Eh, mon, replied Sandy, ‘d’ye see yon field of corn?

‘I do, said the laird.

‘Ah, weel, said Sandy, ‘ye’ll notice that the full heids hang down, an’
that the empty yins stand up.
