A false folk etymology involves Napoleon, who, while invading Germany, asked for bread and was served dark Westphalian rye. According to the folktale, Napoleon declared that this was not suitable bread for himself, the emperor, but was bread () for Nickel (or Nicole), his horse: "". In a variation of the same basic story, Napoleon declared that the bread was no good for him, but was only good () for his horse: "". However, the name "Nickel" is not confirmed for any of Napoleon's many horses. Additional folk etymology grew from a "witty interpretation", proposed by seventeenth-century satirist Johann Balthasar Schupp, that the bread was only "good for "Nicol"", a nickname for a weak or puny horse.
