If nothing else, all three seasons have shown us that once a candidate gets hold of a phrase, they abuse it until the cows come home. There are some phrases that drive me nuts and I never want to hear them again, and others that may only have been used once or so, but they stick with you. What are other people's favorites and the ones they never want to hear again?
Never want to hear again:
"At the end of the day"
Memorable for other reasons:
"screwed the pooch"
"your ass doesn't know if it's sitting on a $5 toilet seat"
