[plt-scheme] Scheme Programming Question (Making an error message)

Jos,

You're wasting your effort in the wrong place.  This person (or a
classmate of theirs, "Scholar") has already posted the question to
cramster.com:

But even better:

  Bonus Point Alert! Earn +4 *additional* karma points for helping
  this annual member.

Why are you answering questions on plt-scheme, when you could be
preparing for the afterlife?

PS: What I'd really like to know is what crackpot professor put out
    a question like this.  Any ideas?
