>I didn't know it was that bad. The problem was the wiring tripped on several times on normal usage, but the landlord said the breaker was fine, and I just gave up, because I couldn't prove otherwise until I got shocked.Then the electrician explained what happened.

Touching the extension cord plugged into the outlet. I think the effect was much closer to like touching a live broadcast antenna, since the whole thing was shorted. I didn't take good before pictures, bt there's still a broken outlet in my apartment.
