Last night, Keith Olbermann did a piece on shoe-throwing, the sort of piece that could only happen on a slow news day. He tried half-heartedly to turn it into a trend story but his guest wasn’t biting and I wasn’t either. Then I remembered the words I saw typed on a Blackberry beside me when C. Ray approached the microphone at the Jazz Fest lineup announcement: “I’m working to keep my shoes on.” If the texter knew he had two city cars in his driveway, at least one shoe would have flown.
