Karl Stefanovic bursts into laughter over a juvenile joke on Today show

Karl Stefanovic can’t control himself as he bursts into laughter over a VERY juvenile joke on the Today show

Karl Stefanovic was left in stitches over a crude joke on the Today show on Thursday.

During a segment about sport, AFL star Shane Crawford made a joke about playing the game with ‘slippery balls’ in winter.

The double entendre was enough to have Karl, 45, doubled over with laughter.

Even his Today show co-host Allison Langdon was laughing along, seemingly tickled pink by the juvenile joke.

‘Mate, we’ve all done it before,’ Shane said with a straight face, which only caused Karl to crack up even more.

‘What are you bringing me up for!’ the breakfast host shrieked. ‘I’ve got a six week old!’

As the men continued to joke about ‘slippery balls’, Allison finally decided to step in and get the segment back on track.

‘Boys, bring it back into line, please,’ she said sternly. 

This isn’t the first time that Karl has showed off his sense of humour on the morning show.

Last month, his cheeky comedy came at the expense of his co-anchor Allison when he made a somewhat awkward joke.

The pair were discussing with newsreader Alex Cullen ‘who wants the pants’ at the desk when Allison made a rather unfortunate comment, which Karl immediately jumped on.

Karl said that his female colleague ‘definitely wears the pants’, which prompted Allison to say she wasn’t actually wearing pants to work that day.

‘Not today. I’m not wearing pants today,’ she said jovially, referring to the fact she was wearing a dress.

Alex said ‘woah!’ before Karl feigned shock at the apparently racy remark.

A clearly embarrassed Allison then tried to backtrack: ‘No, it’s a dress!’

Oh, dear! The pair were discussing 'who wants the pants' at the desk when Allison made a rather unfortunate comment, which Karl immediately jumped on
