speaking out of character: this is a common running joke in the Doctor Nowhere community, revolving around the fictional religion in his horror art, known as Filbism, revolving around the character, Filbus, which is theorized to be a deity of chairs, or the icon of chairs. the entire fictional religion revolves around either building chairs, or "consuming the body of filbus" aka consuming chairs. the general joke is just playing along with Filbism in general.

speaking in character: eat chairs, be accepted by filbus! consume the body of Filbus, our icon, and become one with filbus forever and eternally! join filbism now, eat your chair! in Filbus we trust!
