Germany, lots of carnival. In many regions the current carnival traditions date back to the Napoleonic era and were originally invented to mock the French. In some regions, they date back way further and are more about warding off evil spirits and shit.
The biggest carnival events take place in the Rhineland, with the Carnival parades in Cologne, Düsseldorf, and Mainz on Shrove Monday being by far the biggest single events. (The carnivals in the Rhineland are of the "mocking the French" variety)
Generally throughout the entire carnival season (regionally known as "The Fifth Season"), there are all sorts of carnival parties (basically dress up in some sort of costume and get drunk) and "carnival sessions" (basically big comedy/entertainment shows) with carnival speeches, often organised by carnival societies.
