Joe Kernen, host of CNBC's "Squawk Box," recently used a fake Indian accent and joked about using Indian currency at 7-11 stores in America.

Kernen and his co-hosts Becky Quick and Andrew Ross Sorkin were talking about various currency rates and how India's central bank unexpectedly raised interest rates on their Sept. 20 broadcast, noted

The hosts then began discussing the rupee, which Quick happened to have in her purse from a recent trip to India (video below).

After she showed her rupees to the camera, the hosts started to talk about how Gandhi's picture was on the bills.

At one point, Kernen repeated "Gandhi" in a stereotypical Indian accent.

Quick urged Kernen not to continue, but he asked, "Are they good at 7-11?"

"Stop," said Quick.

"Alright, alright, I won't. Let's look at the people say that all the time. Right? Oh, you're nervous," Kernen replied.

Moments later, Quick told him, "It's insulting."

Kernen answered, "I'm sorry, I take it back. I apologize, before I have to."
