Great streetart: “Wer anderen eine Bratwurst brät, hat ein Bratwurstgerät” - freely translated “Those making others a hot dog, have a hot dog maker.” A pun on words derived from the German saying “Wer anderen eine Grube gräbt, fällt selbst hinein”, which according to Leo means “Harm set, harm done”, never heard of such a phrase. Better translated as “Those digging a pit are likely to fall in it”.
