Royal etiquette Memes

A chemistry pun that's truly inert! The joke hinges on the brilliant double meaning of "noble gases" - elements in the periodic table's rightmost column that famously don't react with other elements due to their full electron shells. Just like royal etiquette demands no reaction to a monarch's bodily functions, helium, neon, and their gaseous cousins refuse to participate in chemical reactions. The commenter's "He He He" response is particularly clever since "He" is the symbol for helium - the lightest noble gas. This pun operates on multiple levels that would make any chemistry professor simultaneously groan and secretly appreciate.
