The inspiration for this design came about because I always thought Pops's head looks like the moon; he always acts and appears as though he is from a different era. Then it brought to mind the old short film, one of the first ever produced, A Trip To The Moon (Le Voyage dans la Lune). This is paying homage to the most famous scene in which an actor, dressed as the moon, has a rocket carrying philosophers crashes into his eye. I thought it was appropriate referencing the space theme that occurs in so many episodes, and as a way to date pops. It also serves as an example of how far we have come in film and television.
