"did you see that guy John Key Richie Mccaw, how embarrassing "
Person B: Oh dear, you fell for the classic John Key trick!
Although he comes across as a soft, modern man, he recently demonstrated that he is, in fact, a hard man, and is prepared to give all in service of his country. He demonstrated this by breaking his right arm in two places at a function, then carrying on as if nothing happened. He then shook the hands of 120 touch rugby players at another function before seeking medical help. Because of this, the phrase "to do a John Key" now refers to a seemingly uncharacteristic act of bravery and resolve.
