Bizarre but True Tales of the Twenty-Third Dimension

This is a true story. One hundred percent of what you are about to read is
documented and certified to be completely true. However, the events you're
going to read about didn't take place in the dimension where you are, but
instead they take place in the Twenty-third Dimension (which, by coincidence,
is a universe parallel to our own). If you were to make the effort to visit the
Twenty-third Dimension you would see another world where people live and
die, love and hate, as well as dance at other people's weddings-as if theirs was
the only dimension that existed. But since we know that we exist, we know that
they are not the only dimension, but just one out of a very, very, very many. This
story is theirs and ours. It has you and me in it. While it's true that, as it is a
parallel universe to our own, we are there, but we are not the same people
there as we are here. We would be if we were to make the same choices and
the people around us made the same choices as we and they do here.
(Unfortunately there is talk of reducing this twelve-trillion-page manuscript to a
more portable size. That chore will be left in the hands of the editors.)
In the Twenty-third Dimension, people are different. For instance, Genghis
Khan successfully ran a preschool. Adolf Hitler, a man who made a nuisance of
himself in the Two-hundred and Seventeenth Dimension (your own) was a sign
painter (as in billboards) in the Twenty-third Dimension, and a very good one at
that. I won't tell you any more, only that he was up for an award. As for Genghis
Khan: with him in charge, the preschoolers quickly learned that nap time means
nap time.
