A fine tradition since 2002...
2009: "Culture eats strategy for lunch."
2008: "Buy the beer first, this job ain't gonna be easy."
2007: "If you want peace, work for justice."
2005: "Pandora and I are on a first-name basis."
2003: "I get enough exercise just pushing my luck."
2002: "Chaos, panic & disorder...my work here is done."
NB: These are certainly not original with me; I just like them.
