Forgive me if I've told this story before. Absolutely true.
I grew up in the Highlands where it was common to go out and shoot your supper, particularly if you were a bit short of a bob or two. One of the great local characters had done exactly that but, unable to find anything straightforward like a rabbit or duck, he'd shot a swan. He talked about it the following night in the pub and his mate had reacted in horror.
" You can't shoot swans---they're protected!"
The answer, after a slight pause, was perfect.
" Well, they might be protected but they're not ******* bulletproof."
