Quotes
"Okay, Americans are hungry. We get it. Well I've got news for you - things are tough all over, people. The President himself has been forced to substitute cube steak for his nightly prime rib, and the only wine available is a detestable Chateau Montrose 2043. But does he whine? Does he take to the streets like a rabid Red? So please, good people, please. Wait in line. Get your food. And then go home. We're Americans! We do not solve our problems with violence."
