[Ken H]

Here's a good one:

"thou subtle, perjured, false, disloyal man!"   

-The Two Gentlemen of Verona: IV, ii

[bjc]

Good ones and on target but I think Oscar Wilde or Mencken would supply more delighfully malignant and vicious descriptions: perhaps we can ask Christopher Hitchens to come up with a few choice accurate but ascerbic adjectives.
