I have given this one (directly, not only posted). Someone reported in the thread that he went around 10 times - seen by at least 1 person.
I don't think I could do it myself though.

-- Drive someplace in your car, at night.
-- Take all your clothes off at some point.
-- Stop under a street light. Not in a parking lot - on the street.
-- Park DIRECTLY under the light.
-- If you are not completely naked - strip now!
-- Get out and walk (not run) around the car. Yes, it's a bright light overhead!
-- Get back in your car and drive away.
-- Report back here on how it went.
