Finally, the prankster has been pranked.
Perennial joker Karl Stefanovic has been given a dose of his own medicine by German model Heidi Klum, who coaxed the Today show presenter into yodeling during an interview, only to break the news to him she was nothing but an amateur.
In Australia for the first time in 15 years to promote her new line of lingerie, Klum finished off an interview by offering to teach Stefanovic how to yodel.
Surprised, Stefanovic agreed to have a try. Klum went first and Stefanovic repeated after her.
"Try a little harder, I tried really hard," Klum said to Stefanovic, who was clearly unimpressed with his first effort.
After a few more attempts, and with Stefanovic's yodelling sounding like a chicken being strangled, he then asked the 41-year-old model: "God that was good, how long have you been yodelling for?"
"I don't really know how to yodel," said Klum, with a grin on her face, knowing she had successfully tricked the man who thrives on making others trip up.
Stefanovic burst into laughter and admitted to Klum: "You got me."
Stefanovic has forged a reputation as someone who loves a prank more than most.
Former Today show sports reporter Roz Kelly was pranked while reading a sports bulletin in 2013 when Stefanovic added an extra line to her script.
"The Blues defeating Portuguese side Benfica 2-1 in Amsterdam, how good are the cookies ... there," Kelly read from the teleprompter.
Stefanovic immediately burst into a fit of laughter, as did co-host Lisa Wilkinson and Georgie Gardner.
Kelly was unaware at first who had been behind the act of tomfoolery, but quickly worked out it was Stefanovic's doing.
 
In April, Yvonne Sampson was also thrown for a loop when Stefanovic introduced her sports bulletin early, when really the show's Celeb Buzz segment was up next .
"Oh you've done it again haven't you," Sampson said to the delight of Stefanovic who was yet again in stitches.
