Gov. Jerry Brown publicly scoffed at Gov. Rick Perry’s attempt to draw Californians to Texas for better business, saying that the ad campaign is “barely a fart.”

“It’s not a serious story, guys,” the Californian Democrat told reporters at a business event, the Sacramento Bee reported Tuesday. “It’s not a burp. It’s barely a fart.”

The classy jab comes a day after the Texan Republican governor released a 30-second radio ad in major Californian cities inviting them to “come check out Texas” for better business and is just one more punch thrown in the ongoing back-and-forth between the two very different governors about whose state presents a better business model.
