It would require immense stupidity
Bale is a footballer.
Ha. True. But also what does he have to lose? The risk/reward balance for diving is a no-brainer. Even if he's caught doing an absolutely nailed-on dive the worst that he gets is a yellow. On the other hand, if you're not caught, you get a free kick (or penalty), the opponents go down to ten men and lose their goalkeeper who is then banned for the next game as well.
Nah - getting caught diving is worth the risk all day long with the rules as they are.

Not sure Pulis will be laughing though!..
