Antiques... Kitchen!

It is said that a Besançon merchant once discovered in an antique shop a cruet with two bottles, one engraved with the letter V; the other with the letter H.
We know that Victor Hugo was born in Besançon, and as a result, our merchant suddenly had the idea that he was in the presence of a cruet that had belonged to the illustrious French poet. Without delay, he purchased the object and immediately offered it to the Victor Hugo Museum, supporting this royal gift with a moving letter ending thus:
"I paid its weight in gold for the Master's oil cruet, I don't regret it, my means allow it."
It was Victor's executor who received this gift; he examined it, and replied to the sender with the following few lines:
"I received your oil cruet; it is comfortable, practical, and of a normal volume. However, the letters V. and H. separately adorning each bottle do not stand for Victor Hugo.
They simply mean Oil and Vinegar. The Museum cannot find a use for your donation, but I think my cook will be able to use it."

Now, the same adventure happened one day to one of the members of the Academy of Inscriptions: a curious little pot bearing these four capital initials was submitted for his examination:
M. J. D. D.
Through patient research, the scholar managed to make this luminous restitution: "Magno Jovi deorum deo"  (To the great Jupiter, god of gods).

- This pot was never dedicated to Jupiter, his interlocutor told him. It simply bears these words:Yellow Dijon mustard. (Moutarde Jaune De Dijon)

The scholarly member of the Institution found the joke in poor taste.
