“The answer to this riddle has a hole in the middle,And some have been known to fall in it.In tennis it's nothing, but it can be received,And sometimes a person may win it.Though not seen or heard it may be perceived,Like princes or bees it's in clover.The answer to this riddle has a hole in the middle,And without it one cannot start over.”

“For an answer which cannot be expressed the question too cannot be expressed.The riddle does not exist.If a question can be put at all, then it can also be answered.”

“Richard was a riddle with no answer, and I was tired of playing a game I couldn't win.”

“You know what your problem is, it's that you haven't seen enough movies - all of life's riddles are answered in the movies."Steve Martin”

“Children are the proof we've been here . . . they're where we go to when we die. They're the best thing and the most impossible thing, but there's nothing else . . . Life is a riddle and they are the answer. If there's any answer, it has to be them.”

“It seems to be very hard for people to live with riddles or to let them live, although one would think that life is so full of riddles as it is that a few more things we cannot answer would make no difference. But perhaps it is just this that is so unendurable, that there are irrational things in our own psyche which upset the conscious mind in its illusory certainties by confronting it with the riddle of its existence.”
