Certainly not easy and requires fast typing, but, see http://www.jetpunk.com/user-quizzes/63858/countries-of-the-world-five-minute-sprint/stats where 1.8% list all countries in 5 minutes:
- countries: 6 minutes
- world capitals: 6 minutes
- us states: 1:30 minutes
- us capitals: 1:30 minutes
- elements: 3 minutes
- 100 most common words: 2:45 minutes
would do it just in time.
I think you need to know the various sections independently so you can type all countries one after the other, for example, instead of going through the complete list alphabetically
