C. S. Lewis in "The Screwtape Letters" describes the real agenda of Saturday Night Life's “humor.”
In Lewis' book his character, an senior evil spirit says:
But Flippancy is the best of all. In the first place it is very economical. Only a clever human can make a real Joke about virtue, or indeed about anything else; any of them can be trained to talk as if virtue were funny. Among flippant people the Joke is always assumed to have been made.
No one actually makes it; but every serious subject is discussed in a manner which implies that they have already found a ridiculous side to it. If prolonged, the habit of Flippancy builds up around a man the finest armour-plating against the Enemy [God] that I know, and it is quite free from the dangers inherent in the other sources of laughter.
It is a thousand miles away from joy; it deadens, instead of sharpening, the intellect; and it excites no affection between those who practice it.
