This a good block.
It were a delicate stratagem to shoe
A troop of horse with felt. I’ll put ‘t in proof,
And when I have stol’n upon these son-in-laws,
Then kill, kill, kill, kill, kill, kill!
– William Shakespeare
King Lear, act 4, Scene 6. Now at the hight of his madness, Lear gets into a frenzy, vowing to track down his two sons-in-law and take them out, repeating over and over the word "kill."
