"I've had Botox, but then again pretty much everyone I know has. To me, Botox is no more unusual than toothpaste. It works. You do it once a year - who cares?"

"I suggest we bring some normality back to this country and say if you are carrying a knife, there must be zero tolerance. If it was up to me, everyone caught with a knife would get an automatic ten year sentence."
