Camy,

Both Huckleberry Finn and Tom Sawyer were removed from the
children's department of the Brooklyn Public Library in 1905 because
they set "bad examples for ingenuous youth." Mark Twain's letter about
the incident is online at:

The Bible and Huck Finn: Letter to Asa Don Dickinson

There have been more recent complaints along the same lines. One of
the funniest I've seen occurred sometime in the late 1990s. A teen ran
away from home and flew to Hawaii. When he was found, he said he got
the idea from Mark Twain. Apparently airlines are the modern equivalent
of a raft. :-)
