The Martin business reminds me of the incident many years ago when one of a pair of burglars hopped over (I think) John Aspinall's 9ft high security fence adorned with signs saying 'Beware of man-eating mountain lions' or somesuch. He was set upon by a pair of man-eating mountain lions. He got out - just - and tried to sue for damages. When asked what he was doing scaling the fence, he said that there was no answer at the front door and so he decided to nip round the back while his mate waited at the front for the owner. Hmmmm.
