RUSH LIMBAUGH: I probably shouldn't say this, but I just -- I don't keep anything from you people. And I got up today, and I started going through this stuff, and everything I look at, 'Don't care, don't care, don't care, don't care.' And the don't care stack is about 90 percent of what I have today. 

[...]

So today I'm going to be working rather than just coming in here and letting it flow. And no, it's not any particular thing out there. I don't know if it's just an attitude, if it's a mood. I don't have periods, so it's not that. Well, I'm just trying to come up with every possible explanation to answer all of the questions that people probably firing at me.
