a good list of minor references is on Wikipedia:
en.wikipedia.org/wiki/Mark_Twain_in_popular_culture
also, please do not forget the many references in modern songs, such as "Tom
Sawyer" by Rush ( a really, really cool song); or Belle & Sebastian's
"This is Just A *Modern* Rock *Song.*" Or the musical "Big River."
Probably there's a list our there somewhere in digital land...
