ok so i was putting in a lightbulb in my room and something was blocking me from screwing my bulb in, so i stuck my finger up there to see what was blocking it.. turns out it was live my finger tingled and it stuck for a few seconds then i pulled away lol today keeps getting worse.
p.s - i also done it on the exact same socket when i was 7 years old same outcome. same feeling. im chuck norris.
