British actor SIR Michael Caine has revealed the secret behind his legendary success with women - he made them laugh. The Batman BEGINS star has been happily married to his wife Shakira - a former beauty queen - for 33 years, but still has advice for younger would-be casanovas. He says, "I think one of the greatest things you can do if you want to be a seducer is make her laugh. "People say give her diamonds but if you make a woman laugh you've got relaxation and she feels at home with you and then get them to take their shoes off. "Once they take their shoes off, that's it."
