Avignon festival
The Festival d'Avignon is going on right now through July 27. It's a theater festival, and there are literally hundreds of plays being put up all over town. Even in the Palace of the Popes. (IANAC*, but why did the Pope need a Palace? With both small and large treasure rooms?)
Also, from a person who shall remain nameless, on the Tour de France: "If you think riding in the tour is hard, try watching it!"
* IANAC - I am not a Catholic.
