If you have lived in America or Europe from December 15 to January 02 and roamed about the city in the evening, rather late evening, you may have witnessed some men and women doing it. During year 1966, I was in Düsseldorf (Germany). One evening I and a Pakistani friend went for a walk after dinner. On way we saw a crowd along the road making noise after intervals. On going near we saw a woman and a man going one by one towards a lamp post swiftly and then returning muttering “Oh I could not climb up this time”. This was being repeatedly done. We didn’t have our camera with us so we missed the chance but here you can enjoy another such incident.
