We wrote a post a couple of weeks ago called "Cashing In On The Campaign" advising you to take advantage of the heightened interest this year in the presidential election and in politics more broadly. But never did we think that this advice would be put into practice as literally and as successfully as it was by the Waldman siblings--ages 3, 5, and 6-and-three-quarters--who did exactly what entrepreneurs are supposed to do: find a perfect business opportunity and quickly, and with low-cost, move in to make a killing.

In their case, the Waldmans, who live in Washington D.C., found numerous news- and cameramen around their house late last week camped out in the sweltering August heat in front of the house next door, which happens to belong to ex-vice presidential hopeful Sen. Evan Bayh (D-Ind.). Displaying remarkable business acumen, they opened shop: a lemonade stand, to be precise. One dollar bought (roughly) a pint. ABC News reported that the cameramen especially were big fans.

What lucky situation will create prime conditions for your lemonade stand?
