Munich. A man in a disco in Munich urinated on a power socket on Thursday evening and caused a blackout.

According to police, the man sneaked behind the bar and urinated on a multi socket plug. Then the lights went out but the man was not injured.  As to why he did this, the police do not know. When the owner of the club asked him, he simply started to laugh. "Perhaps both of them held an old grudge", says a spokesman of the police.
