Joking is a dangerous game
From Gnomon Chronicles
Jokes are a dangerous game. In general I am against jokes about serious topics.
Jokes can raise awareness, which is a good thing.
But they necessarily raise emotion, which is a bad thing (f you believe, as I do, that rational thought is highly survival-oriented, emotion not so much).
And, like oracles, jokes can be interpreted *any way one likes*, which diminishes or ruins the awareness value.
