In Newcastle, UK there are signs along the tramway route that say:
"Touching Wires Causes Instant Death", followed on the next line by
"L200 (pounds) Fine"
Which is likely to deter miscreants the most? Death or a 200 pound fine? How many folks have paid the 200 pound fine?
I have pictures of this sign that some beaucratic incredibly thought up.

Nothing funny! You touch the wires, die, and L200 get deducted out of your estate value.

In Upton-Upon-Severn, England, the following warning: "The owner of a dog which befouls the footpath will be subject to a fine of £5.

Shoot, I can top that. About two months ago, right here in Midwest, U.S.A, my neighborhood convenience store was advertising a sale on its big sign:

"Lays - 2 for $5."

I almost stopped on my way to work.

'You touch the wires, die, and L200 get deducted out of your estate value'

LOL!! Yeah, that'll teach you..

If you die AND get a fine don't come running to me to complain.
