Throwing Cliches Around like Bowling Balls

If I've said it once, I've said it a millions times: we need to avoid cliches like the plague.

Having said that, I noticed yesterday two interesting cliches in radio discussion of the Obama speech. (I had a several hour drive in the AM.)

It seems that Sen. Obama threw Rev. Wright under the bus, but threw his own grandmother overboard. No one, to my knowledge, was thrown from the train (OK, maybe Ferraro, but I didn't hear anyone in talkradioland use the term.)
