The Google group (used to be Usenet newsgroup – remember?), rec.puzzles has Rare Entries Contests, the best of which is run by Mark Brader. The goal is to answer trivia questions with the least popular answer. For example, the last quiz asked the following:
0. Pick one: heads or tails.
1. Name a country that, according to the current CIA World Factbook, is divided into more than 35 states or provinces as defined in (the revised) rule 4.1.2.
2. Name one of the 13 ranks in the standard deck of playing cards used for games such as bridge.
3. Some organizations have names containing a two-word phrase where one word specifies a color and the other a shape (either a geometrical term or a term commonly used for a stylized shape). Name a color/shape combination currently used in this way.
4. Give an English word of one syllable that names a color.
5. Name a person who at the age of 50 was playing professionally on a regular basis in some team sport in a league with a high standard of competition. Â (Events limited to players over 40, say, would not qualify as a high standard of competition.)
6. Name a country some of whose de facto land territory is also claimed by another country. Â Note that rule 4.1.1 applies to both countries; this question is about border disputes, not separatism.
7. Name a person who was assassinated during the 19th century and, at the time, was the head of state or head of government of a country.
8. Name a unit of measurement which has been routinely used to express barometric pressure readings (of the atmosphere on this planet) either to the general public or to meteorologists.
9. Give a single word used in English as a noun to designate a type of gun (in the sense of a handheld firearm). Â “Type” does not include brand names, numbers, or any forms derived from these.
