See my comments in post 1540.
I thought I heard another "dig" from W, I don't know if anybody else agrees with me. He said that the Clinton's greatest achievement was the wonderful daughter, Chelsea. Now, if I'd been president for 8 years and had been desperately seeking a legacy, I'd want to hear a little bit more about my great achievements, beyond raising a daughter. Maybe I'm wrong about that, but it seemed like faint praise to me.
