That's certainly wise advice to give the young'uns Phil.
It doesn't seem like that long ago when the police operated a 'shoot to kill' policy in those parts (being shot in those parts is no fun either, I would imagine), and it wasn't unusual to find a few likely lads lying, as Bobby Dylan says, in a pool of bullerrrrd, next to their half erected item from the scout troup.
Nowadays though, you'll get away with a hooding and a dodgy connection to a 12V cattle prodder, which after all is right in vogue these days.
