Their expulsion is so important for health that to release them is to enjoy them. Thus, doctors order us not to suppress them, and for this reason the Roman emperor Claudius Caesar put forth an edict commanding that no one, on pain of death, and even if dining with the Emperor himself, should hold in his farts, given their importance for health. (Others say that this was done because of the special respect due that honorable gentleman, the asshole.)
Where would we be without our assholes? We can live without almost any other organ, but not this one. Yet it never gets the appreciation and gratitude it deserves, but is scorned and abused instead.
