This is a simple game that's suprisingly entertaining, especially on long hikes, horse rides, etc.
Some one thinks of a question or answer, then annouces that they have a question/answer. Some one else then thinks of an answer to the unsaid question (or a question for the unspoken answer). The question is said outloud, followed by the answer. Sometimes it's lame, but many times you get some pretty awesome results. Real life example: P1- "I have an answer" P2- "I have a question" P2 - "Why haven't we reached the campsite yet?" P1 - "Dinosaurs."
