Interesting. Wayne Carey would disagree.
In his book, "The Truth Hurts", Carey mentions a trip he took to Vegas with a couple of mates in 2002, after he retired from North Melbourne. On this trip, Carey and his mates were introduced to cocaine by a couple of large African-American males. Carey mentioned one of the males played professional football. After spending a good 3-4 hours with them partying, and with the affects of the cocaine well and truly kicked in, one of Carey's mates told the professional footballer that, "Wayne is pretty big back in Australia. He's a champion Aussie Rules Footballer." After the American pro footballer took no interest in Wayne being a big hit back home, Wayne's drug affected head suggested to the pro footballer to position themselves 30m apart facing each other, and on their count, both Carey and the pro footballer would charge towards each other and the first person to pull out loses. Challenge accepted.
Wayne reckons neither he nor the large American Footballer pulled out, but Wayne continued standing, while sending the Footballer flying on his backside, who was gasping for air and badly hurt.
