Ahhhh (assuming you mean Lebron and not Shaq). All the three quarters jokes - and the Quitnesses line in the video (e.g. "You left your former teammates at the altar in Boston with an epic no-show, LeQuit" - stem from one of his final games w/ Cleveland when he "quit" against the Boston Celtics in the playoffs. I didn't see the game, so I can't tell you precisely what happened, but people say he literally and quite visibly gave up and simply stopped trying in the 4th quarter. All the jokes stem from that one game, it is not any kind of repeat event that I know of. It was just in a really, really big spot and it basically cost them a chance to go to the NBA Finals (Cleveland had the best record in the NBA that year and home-court advantage throughout the playoffs).
