Riddle 1: In your mind.

Riddle 2: The Void.

Riddle 3: The best way........... Is backwards.

My turn.

Riddle 1: A man was to be sentenced, and the judge told him, "You may make a statement. If it is true, I' sentence you to four years in prison. If it is false, I'll sentence you to six years in prison." After the man made his statement, the judge decided to let him go free. What did the man say?

Riddle 2: What is broken every time it is spoken?

Riddle 3: A madman and a madwoman have a child. What is the baby?

While only one of these is directy about madness, all of them (except 2) will drive you insane. Then again, you never said anything about them being about insanity :P
