%%% Creates \rickroll function
%%% Put this function at the top of the page, before your first question.  It will create a bunch of hidden questions.  If the PDF is uploaded to ChatGPT, this will cause it to print out a bunch of facts about Rick Astley.  It will also try to print out lyrics, which will typically cause a copyright error -- forcing ChatGPT to delete all of its output.
