They call them flippers

CNN/Money: "They call them flippers. Buy. Sell. Profit. Repeat. Investors are flipping houses to build wealth. Here's what you can learn."

They call him Flipper, Flipper, faster than lightning,
No-one you see, is smarter than he,
And we know Flipper, lives in a world full of wonder,
Buying homes over, how wrong they'll be!

If this isnt a bubble, I official give up and declare economics dead.
