fucking love king lear. I could help you out a tonne if I was at home, I have about half a dozen essays and loads of notes on it.
My favorite quote would definitely be:
"My wife is slippery" (mainly because of the way my English teacher used to say it) and then it goes something like "she has been sluiced by my next neighbour, sir smile". Something like that; it's been 4 years since I last read it so I could be wrong.
Shakespeare was the master of our language. A hero of mine actually.
