These remind me of an American comedian, Bill Engvall, who does a routine called "Here's your sign".  His theory is that people who ask stupid questions should have to wear a sign. lol  Anyway I'm guilty of asking some pretty stupid questions myself so I find his routine pretty amusing.

Here is link to a sample of his comedy:  http://www.youtube.com/watch?v=upXayzBPuzM

What a strange illusion it is to suppose that beauty is goodness.
