My all time favourite has just become Hugo Chavez' stand up comedy stylings while at the UN General Assembly podium TODAY.

"24 hours ago the devil was in this room. 24 hours ago the devil was at this very podium. I can still smell the sulfer of the devil . The devil I refer to is the President of the United States George Bush.
It still stinks..."

it gets impossibly funnier, like something Amos or catspaw could write.
