I live in Augsburg, Germany. We have „the king“. He just declared himself king of Augsburg about 30 years ago and everyone just went with it. He spends his days walking through the city looking after the wellbeing of his people. Here’s a video-portrait by the local newspaper for his 70th birthday (in German)
In German there is this kinda obscure phrase „Pferde vor der Apotheke kotzen sehen“, which translates to „seeing horses puke in front of the pharmacy“ used to denote something highly unlikely, because horses can’t puke and especially in front of a pharmacy where they could get something against their nausea.
