I guess this is in response to Sarah Palin calling Herman Cain the flavor of the week:

“So he’ll get a lot of attention, suck up a lot of oxygen for a while,” Cain said of [New Jersey governor Chris Christie], adding, “And at the same time, you’ll see black walnut moving up the charts.”

Cain joked, “I can eat black walnut all the time — it’s not a flavor of the week! It’s not that heavy. You can eat it on the cone or in a cup.”

Who says Herman Cain is a one-note candidate? The pizza man is diversifying into ice cream!
