Joanna found this great Shakespearean insult generator. I was clicking through it and ran across one that was just perfect for Dear Leader, er, B. Hussein Øbama:
[Thou art] a most notable coward, an infinite and endless liar, an hourly promise breaker, the owner of no one good quality.
(From All's Well That Ends Well.)
It just spoke to me.
Excellent quote, and the most apt description of our President since I named the donkey in our manger scene Hussein last Christmas.
