In Germany, Karneval reaches its peak each year on "Rose Monday" (Rosenmontag), the day before the Mardi Gras celebrations in other parts of the world. Parades with elaborate floats characterize Rosenmontag in the Rhineland.
Here, via Spiegel Online, is a float from this past Monday's parade in Mainz.
Continuing the George W. Bush theme, this float from the parade in Düsseldorf depicts W. getting a whiff of Ahmadinejad's "armpit [Achsel] of evil." [Via Wikipedia.]
