Rush Limbaugh says the darndest things

[Tino]

How can you tell when Rush is being humorous, and when he is making a serious point?

Like the Daily Show, after you've listened/watched a few times it usually is self-evident. Grandiosity is often a clue. The more grandiose, the less serious. Occasionally it is is not clear, and listeners usually ask, and it gets subsequently clarified. Often an item will reflect a recurring meme within the show, and that is often an indication as well.

If you watch the Daily Show, how do you know when John Stewart is being humorous, or when he's making a point or delivering straight news?
