Let this serve as a reminder to celebrities to put their cell phones on silent before going into an interview. Earlier this year, Brad Paisley and Carrie Underwood co-hosted "Country Countdown USA" with Lon Helton, during which Brad's cell rang. Not a big deal, unless you've got an unusual ringtone, such as a duck quack, which was the booming sound coming from the "Camouflage" singer's phone.

"That's actually Darius Rucker calling," Brad admitted, before clarifying, "That's the same ring for everybody. Sorry, Darius."

However, Helton jokingly questioned the validity of Brad's explanation and asked Darius if he bought it. "I don't believe that," Darius answered the award-winning radio host with a laugh. "For some reason, I'm the quack only. In his wonderful brain, it's very funny to him. I love him. I love Carrie, too. What a great two people to represent our industry."

Darius is, of course, is referring to the 46th Annual CMA Awards, which Brad and Carrie will co-host for the fifth year in a row. The show airs Nov. 1 at 7:00 PM ET on ABC.
