Radio host pranks co-host by pretending they're on air, spewing curse words

A prank isn't so fun when your job is on the line.

Morning radio hosts Alex Duffy and Emma Louise Jones started their show as usual, with a delightful Sia song. It was only when Duffy started to rattle off curse words that Jones started to freak out.

"Alex, it's only eight o'clock!" she said.

Fortunately, it was all a prank — they weren't actually live. But when Duffy finally told Jones they weren't on the air, she still wasn't laughing.

"I literally want to call you every word on that list," she said.
