"WRONG WAR, WRONG PLACE, WRONG TIME!"

"YOU CAN RUN BUT YOU CAN'T HIDE!" 

"YOU GOTTA HAVE RESOLVE TO WIN THIS THING!"

"YOU PUT A LAWYER ON THE TICKET!"

"AIN'T GONNA PASS NO GLOBAL TEST!"

"THEM CANADIAN DRUGS COULD KILL YA!"

"IT'S JUST NOT CREDIBLE!"

"HE'S GONNA RAISE MY...AHH...I MEAN YOUR TAXES!"

"HE NEVER SHOWS UP TO VOTE!"

"HE VOTED FOR IT BEFORE HE VOTED AGAINST IT!"

"YOU CAN'T LEAD THIS COUNTRY IF YOU CHANGE YOUR MIND! (BLUES)"

"YOU CAN'T BE POPULAR AND BE PRESIDENT! (BLUES)"

"WE DON'T NEED MASS ARMIES ANYMORE! (WALTZ)"

"IT DENIGRATES AN ALLIANCE TO SAY WE'RE GOING IT ALONE!"

and one that a lot of people fell out of their chair laughing at last night...

"I'M A GOOD STEWARD OF THE LAND!"

Of course you have to scream all these to get the right effect.
