Several of the Republican presidential contenders were recently asked the question: how much is 2 + 2? Here were their answers:

Romney: It used to be 4, but now it’s 3 here in Iowa, though next week in New Hampshire it’ll be 5.
Gingrich: It’s whatever I say it is
Bachmann: It’s 6, has always been 6, and even though the liberal media have accused me of once saying it’s 8, I never said that
Paul: It’s irrelevant, because once we get rid of the federal government, we can create a new number system
Perry: Um, uh, give me a minute
