The simplest explanation

The TEMPLE of monkeys in India.

Really, what's seems more intuitive/ credible at this point?

Bhajji somehow forgot that a large number of Indians consider monkeys holy, and in a moment of heated passion in a tense game, revealed his racism by pulling out from the depth of his vast yet largely unused racist vocabulary, a very non-Indian, non-Australian slur to mentally unsettle Symonds (who, by the way, is a very vocal and intimidating Australian cricketer, and also had the nerve to not walk when the nick off his bat was heard way back into the crowds.) Bhajji chose, from all the time he's had in his career, this moment when he was batting in the lower order to save a test match, to turn racist.

OR

Ponting, who didn't walk for his catch down the leg side, who claimed a fake catch himself and confirmed a fake catch by Michael Clark (all in the same record-tying game), devised a clever way of striking two targest with one blow - ridding himself of his nemesis in the series, and taking the focus off the terrible umpiring and his own sportsmanship.
