  This is a summary of theoretical plenary contributions to the biennial hadron
physics conference Meson2006, which was the ninth in this series. The topics
covered in the meeting include low energy pion-pion and pion-nucleon
interactions, photoproduction and hadronic production of light mesons and
baryons,in-medium effects, recent developments in charmed mesons, charmonia and
B mesons, the status of exotica, and some related topics such as final state
interactions. In this contribution we review and summarize the plenary talks
presented by theorists at the meeting, and emphasize some of the main points of
their presentations. Where appropriate we will add brief comments on some
aspects of QCD spectroscopy. Finally, following tradition, we conclude with a
new Feynman story.
