There is a list somewhere of every single email with the words cheese , pizza , domino ' s , pasta , etc . There is no way that regular humans talk about Italian food that much . Plus the way it ' s used is the exact phrasing as how the code words are used ie . Play dominoes on cheese and pasta <| sep |> The round area has a whitish residue , which can be scraped off with a fingernail . I have been tempted to taste it . But am too afraid to . The long rectangular areas have a grayish residue that is pretty much soaked into the wood . There are some scrapes in the bottoms of those areas that I don ' t think we ' re from carving . The two smaller area above the concave circle have a brown residue , but no scrape marks . Those two small areas are only half as deep as the larger ones . The box seems to have no smell , except for a slight wood smell .
