What do you feel the `println` statement here (and in the `else` branch below) adds? Depending on the value of `userName`, a different result will be shown by `printer print` anyway, so if the viewer gets the correct answer s/he will also be able to correctly predict which of _these_ `println`s will be displayed.

By which I mean, I guess, that it does not seem to add a twist to the puzzler but just makes it longer. How about
```
printer print {
  if (userName == "root") "I am the Master of the Universe!" else "Hello, world!"
}
```
?
