There are tons of lists produced at the end of the year and especially at the start of a new decade. So here are mine for whatever they are worth ...
Favorite Things in the 2000s
Economists --- Andrei Shleifer. While I disagree with different aspects of his arguments, I think there is no other economists over the past 2 decades that has made me think more seriously about my own research in comparative political economy than Shleifer. The other nominees would be Vernon Smith (a true life-longer learner whose idea of ecological rationality is among the most significant ideas in contemporary economics), Bob Higgs (and his idea of regime uncertainty) and Avner Greif (and his development of institutional analysis). In the 1990s, joining Shleifer would have been rational choice scholars such as Jon Elster, Russ Hardin, and Barry Weingast.
Books -- tie between Chris Coyne's After War, and Peter Leeson's The Invisible Hook, with honorable mention going to Bill Easterly (both The Elusive Quest, and The White Man's Burden) and Deirdre McCloskey, The Bourgeois Virtues.
Sports Moment --- GMU defeat of UConn to make the NCAA Final Four, followed by Yankees winning World Series in 2009. Honorable Mention: Roger Federer's performances at Wimbledon throughout the decade, and the 2002 UConn women's basketball team led by Sue Bird (undefeated national championship season).
Best Movie --- Lord of the Rings trilogy, with sentimental honorable mention to Juno, Superbad (I know, but I laugh at those movies), and Stranger than Fiction (I love the scene where Will Ferrell covers Whole Wide World)
