Australian TV presenter Karl Stfanovic and co-host of Nine Network's breakfast show Today, pulled a classic Anchorman Prank on his colleague Roz Kelly during Thursday morning's show.

While reading her live teleprompter script about a soccer game in Amsterdam, Kelly suddenly stumbled upon the line "how good are the [hash] cookies there," finish the sentence on the air before she could comprehend it.

"Karl, you've won the battle. The war has just begun, though!" Kelly told Stefanovic.
