You can get a yellow flag for celebrating the wrong way. You can get a yellow flag for simply spinning the ball in celebration. You touch a referee after a game, that's a fine. But you actually CAN'T get fined if you completely run over one because he decides to stand right in front of you as try to make a highlight reel catch. That's part of the reason this sequence is so entertaining.
Referees can't stick any defense whatsoever.
