The Australian former sports star - who fronts advertisements for the Australian lamb industry on television and releases a comedy video every year to mark Australia Day - has released a spoof music clip based on Aqua's 'Barbie Girl'.
He also appears in a 'national address' in which he rants about how he is "sick and tired" of certain celebrities. In the video, Kekovich says: "Things have really hit rock bottom in popular culture.
"For example, the gossip mags have gone googly-eyed over Shane Warne, who went from bowling overs to makeovers, to get his leg over, bleaching his pearlies for [Elizabeth] Hurley. The old Warnie would never have chosen a starlet over a cutlet. Or tweeting over eating."

Kekovich continues: "And is it any wonder Charlie Sheen's lost his sparkle, when he's always off his chops... we go Gaga over a lady who wears a dress from lamb instead of eating it and we talk of Kim Kardashian's over-exposed nuptials.
"We salivate over the TV trial of Michael Jackson's doctor. If only Jacko had popped chops instead of pills, he might still be with us, and a lot less pale and anaemic. What kind of society are we living in when you can win one of those dancing talent shows without doing the lambada? Popular culture is so un-Australian. I've decided to create chop-ular culture instead!"
He told the Herald Sun that he would happily have Warne over to his house for a barbecue on the public holiday on January 26, but admitted that he would be unlikely to turn up.
Kekovich has previously used his Australia Day 'national address' clips to launch tirades about the world economy, diplomacy and global warming.
