It's been suggested on occasion that I need to add a sentence to my signature that says something like ' Warning, hair trigger sense of humour. - liable to go off at any moment!'

My sense of humour has got me into trouble all my life - and it still does......... ah well, I enjoy it anyway!

Like you, I don't understand why people do these things and I firmy believe they need to have a degree of honour and ethics kicked into them with a few size nine boots or knocked into them with a few heavy blows from a tonfa baton!

If that doesn't work, I guess the next best thing to do would be to tie the bastards to a tree for Leopard bait.
