Commonness

Bookends is the forty-sixth most common still life in Achim Flammenkamp's census, being less common than dead spark coil but more common than elevener.[1] It is also the fifty-third most common object on Adam P. Goucher's Catagolue.[2]

gollark: We created a channel in which you are not allowed to have opinions. I removed a person who had an opinion.
gollark: I successfully "moderate" another server. Observe.
gollark: But I have a mostly useless Discord bot!
gollark: Obviously I should be promoted to superadmin as a replacement.
