Mark Twain has no Bacon Number.
Not quite. If you use The Oracle of Bacon
...he's got a Bacon number of 4!
Anyone know what Google allows to use as links? The Oracle of Bacon uses only feature films as default, but can include documentaries, TV shows, and other things through the options. For example, Harold P. Warren, the writer and one of the stars of "Manos: The Hands of Fate" has no Bacon number by default, but a Bacon number of 4 if you include documentaries.
