NOFX is always so surprising in their lyrical abilities. Just some pop punk band with the same beat in nearly every fucking song (except when they ska it up) and a melody/harmony that sounds like Broadway music. But damn are their lyrics smart -- simple without being sophomoric (take note Jonathan Richman), and preachy without sacrificing humor and fun (looking at you Anti-Flag).
"The Idiots are Taking Over" is another good one. So relevant today but it was written during Dubya's tenure.
