You are the fourth or fifth person in the last 24 hours who has resorted to toilet imagery regarding Sarah Palin. What is this fixation on toilet functions? You guys just get toilet trained or what? She'll do what she thinks best. You can expect to read about it, when it happens.
I also find the scatological references juvenile at best.
There's another old saying, that comes close to the one we're trying not to repeat: “fish or cut bait”. Sarah is an experienced fisherman. She knows when it's time to fish. Meanwhile, it seems she thinks the bait still needs tending to.
