LOL. It's funny you mention that because the other night some talking head was trying to say it was a bad day for the prosecution, complete with reasons, etc. and I thought, they didn't so carefully parse Clinton's words but let him get away with the meaning of "is" and oral sex isn't really sex. Sheesh.
You know... the way the brain works when you're in a stressful situation like that... you're going to forget and remember things... I think its only normal.
