A Texas woman went into jaw surgery to correct an overbite, and while she got her new smile, she got something she did not plan for: a British accent.

"I was very shocked," she told ABC News. "I didn't know how to take it. I was very confused. I said 'Ya'll' all the time before the accent. Once I got the accent, I started noticing I'd say, 'You all.'"

There is no known cure for the condition. Although the accent can diminish over time, it can be permanent.

To me, it sounds like she has already been cured, unless it's a C0ckney accent.
