Help with hamlet paper?

in my paper i have to defend this point: Hamlet is only pretending to be crazy, putting on an "antic disposition" as he says in I.v. This is a 2-3 page paper and i need 5 quotes, however you do not have to give me exact quotes, a simple "around this part" will suffice, i can find it from there. Or you could just provide me with points about the above statement. any help would be much appreciated.
