Paul Krugman is an innovator in this field. The other day he had that one about how inflation is under control if you remove, food, energy, used cars, and everything else normal people use. That's basically all my stuff!

Also, obligatory GDP joke that's been bouncing around the internet for a while now:

As they're walking, they come across a pile of dog shit. One economist says to the other, "If you eat that dog shit, I'll give you $50". The second economist thinks for a minute, then reaches down, picks up the shit, and eats it. The first economist gives him a $50 bill and they keep going on their walk. A few minutes later, they come across another pile of dog shit. This time, the second economist says to the first, "Hey, if you eat that, I'll give you $50." So, of course, the first economist picks up the shit, eats it, and gets $50. Walking a little while farther, the first economist looks at the second and says, "You know, I gave you $50 to eat dog shit, then you gave me back the same $50 to eat dog shit. I can't help but feel like we both just ate dog shit for nothing." "That's not true", responded the second economist. "We increased the GDP by $100!"
