Prosecutor: Ms. Blogreader, did you have a meeting at the White House with Wesley Wrongdoer any time before July of 2003?
Ms. Blogreader: No, Mr. Prosecutor, I don't recall any such meeting.
Prosecutor: Are you sure? Think hard.
Ms. Blogreader: No, Mr. Prosecutor, I have no memory of any meeting at the White House with Wesley Wrongdoer before July of 2003.
Prosecutor: 'Cause see, I have this Secret Service log book here, and here's your name, and the time you arrived, and the length of your meeting with Wesley Wrongdoer. And it's signed by you. Twice.
Ms. Blogreader: Oh, THAT meeting.
Like I said, people forget things. But exchanges like this, well, they just don't go over well with perjury juries.
