This may beat every odd Washington Journal caller question I have ever heard:

when a young woman in Sioux City asked Romney to make a candy known as Pop Rocks more accessible … Romney ran with it.
“I used to remember those. It’s been along time since I’ve had Pop Rocks,” Romney exclaimed, and then transitioned to a joke about President Obama. “There are a lot of things I can blame on the president. But I’m not going to blame him for getting rid of Pop Rocks. I’m afraid the market just wasn’t there.”
