Hello!

I got the joke and I think it is funny!!

In case you wonder what the Rosetta Stone was:

The Rosetta Stone was a stone found in an expedition 1799 by the scientist Thomas Young in Rosetta in Egypt. It had text written in 3 different languages Greece,Demotik(early primitive form of Egyptian) and Hieroglyphs. And one day they figured out that they all said the same thing and that was the key that enabled us to finally decode the Egyptian Hieroglyphs.
