is kind of simple
you post an answer, and the next person will provide a "funny" or "Clever" Question to that answer
for example, let's say that the previous poster "before me" posted
"My lips got wet"
so I post
"what happened when I came close to Grandma to whisper to her happy 100th birthday?"
than now I have to post an answer right below the question
--------------------------
my answer is...................................
Everything was white
