Baeckerschupfen (ducking of bakers), early type of punishment for bakers who produced bread that was either too light or low-quality, known since the 13th century. The baker found guilty was put into a basket and was immersed in water or in refuse. The last Baeckerschupfen took place in 1773 in the Rossau (part of Vienna).
