What is Shakespeare's most famous quotation?

Answer:
"To be or not to be? That is the question."
"That which we call a rose by any other word would smell as sweet."
"All the world's a stage, and all the men and women merely players."

There are many. However his main characters' speeches are particularly good. Read King Henry's speeches in Henry V to get an idea. Or anything from Hamlet.
