Not everything can be explained by words. That why we have pictures.
This happens to be one of those pictures which should never be explained by words.
When you have three heads staring at a couple of drawings that look like phallic symbols, the only explanation one can conclude is that “We are dedicated to our work”. Had we dedicated more time learning the skills of drawing, we would know that human silhouettes cannot be correlated to long cylindrical shapes.
With that I’m happy to conclude this final clue for our next project.
