Yeah, nothing disrespectful in it - just one of Mason's comedy routines. He likes to be the joker in the pack, everybody's friend. Didn't do Kitey any harm.
What it DID do, however, as has been pointed out in another thread, was completely take our focus away from the game. Up until that point in the second half we were on top, pushing to score first and build on our two-point lead. We didn't cross the line (no surprise there) and then a Penrith player got injured, which meant there was a huge delay before that scrum feed - which should never have happened. It was a Penrith feed and the refs should have just got on with it. But they didn't, and so Mason shimmied into the spotlight. And we lost our concentration. Next thing you know, the Panthers ran in two quick tries. Game over.
