Urinating on the electric third rail of a train track can cause electrocution.
Although it is possible to electrocute yourself by urinating on a third rail, you would have to stand unrealistically close to the rail to do it. In most instances, a urine stream would break into droplets before making contact with the rail.
(This concept was tested with an electric fence in episode 14 and that version of the myth was confirmed. Distance is the key.)
Using an electric eel-skin wallet will cause a static charge that will cause the magnetic strip on your credit cards to fail.
Most eel-skin wallets are not made from electric eels, but rather from a fish called a hagfish which does not produce an electric charge. Data written to a set of test cards was not affected in any way.
