That's a good question.  I was sensitive to it.  But I think we want to motivate the CBN (and make it obvious with the debug line, which beginners can try out).

The answer choices are simple, which balances the extra source code.

The misdirections are: who is the user?  After all, paulp is Master of the Universe.  You look at the "print" and convince yourself it's paulp.  It's just a CBN, evaluated twice.  Choice 3 says there's no label.  Is there a label?  Oh, that's just a CBN, too.  But it's only used if the boolean is true, and it defaults to false.  (And at this point, the eye is long past the error.)  So it must be 3.  Unless it doesn't compile?  Let me see if it compiles, but I won't actually run it.  Is that cheating?  Hey, it compiles!

But I have to say, showing with and without the boolean arg is also very funny.  It makes you go huh?

Seeing "I am Master of the Universe!" twice is funny, and there's also payoff in excluding that from the answer, because it's kind of like the bad guy answer.  The contrast with "hello, world" is funny.

Let me try it out, you may be right.  Getting these puzzlers pitch-perfect is really a lot of work!

Maybe Puzzlers should open out of town and workshop it for several weeks.
