Just look at the Qualifying Exams questions!
History: Describe the history of the papacy from its origins to the present day; concentrate especially but not exclusively on the social, political, economic, religious, and philosophical impact on Europe, Asia, America, and Africa. Be brief, concise, and specific.
Medicine: You have been provided with a razor blade, a piece of gauze, and a bottle of Scotch. Remove your own appendix. Do not suture until your work has been inspected.
The rest of the questions are just as Chuck Norris tough (and funny!).
Thanks to @eric_andersen on twitter for this.
