Jack's attempted excuse was that he said it, into the camera, to garner heel heat in the match with Hook, which of course made no sense whatsoever for the story, and only Punk, people in the company, or smart marks would understand this reference alluding to Punk dissuading him from using real glass in real life backstage at a previous show. But Elite ally Jack clearly couldn't resist taking a shot at Punk. And why not? They all got away with it for so long, it'd be worth it to make Punk snap.
