He had an accident while jogging, resulting in scratches and the eyepatch. The caption of the picture, which was posted on Twitter, literally said “Am curious/excited for the memes”. His PR knows how to catch the attention of the internet lol
the caption was way more than that, it started with a quote of the beginning of a popular German proverb on Schadenfreude:
“Wer den Schaden hat…” - “Who has the damage…”
The latter part of the proverb exists in two versions, the more benign one ends in “…braucht für den Spott nicht zu sorgen” - “…doesn’t have to ask for ridicule”, the more cynical version ends in “…spottet jeder Beschreibung” - “…is ridiculous beyond description”. Adding appropriate ending was left to the reader.
To be honest, I was surprised of seeing such a sense of humour in Scholz and his PR team, the jogging accident must have scraped off some of the Teflon he is usually coated with.
