 FACT: In this episode, the character Rene/La Grenouille states that  the Cognac "LEspirit de Curvoisier" was first drunk by Napoleon at  his coronation in 1802. Unfortunately it would appear that the  scriptwriters misread the calendar. Napoleon Bonaparte had  effectively taken power in France in 1799 as "First Consol", but he  only assumed the title of "Emperor of the French" as Napoleon I
