Why do you think it was a joke? Was Herbert already disqualified beforehand, or dived out of the competition, that he could afford not bothering about being disqualified, and hence just "joked" with judges instead of doing his proper performance? Are you sure he would denonce himself if he were not cought at it? I would trust it was really a joke, or judge testing, if he did it after discussing it with an AIDA official before the dive, but have really hard time believing such claim if nobody was informed, and if he was regularly competing. Frankly told I am little bit disappointed hearing he attempted to cheat, because it then puts all his previous dives in bad light too. Especially because there was already an incident at his No Limit record where they faked the record dive, while in fact doing it the day before it. I am not telling I do not trust Herbert, but I think the "joking" was definitely not a good idea.
