A good rule of thumb: Don’t piss in public places. Another good rule: When in a foreign land, obey local customs with regards to pissing. Also a very good rule: Don’t piss on the electrified rails of UK train lines.

Don’t follow this advice and you could end up like this poor sap: A tourist in Vauxhall, visiting London to brush up on his English, whizzed on the charged rail and took a 750-volt charge to the nuts, dying instantly.
