Shaz was explaining to a caller how she's always reminded of g-strings when her ozzie mates use the word 'thongs' instead of 'jandals'.
But then right after, as in literally right after talking about g-strings, Jono tried to be funny and did a g-string gag, not realising he just repeated what Sharyn's already said:
Oh, the amount of times I've been to BBQs in Australia...they're like, just bring your thongs and I turn up in a g-string.
Shaz called him out and told Jono he just literally copied her gag. 😂
