WHY does President Joseph Ejercito Estrada always wear a wristband on his right hand? According to a popular Filipino joke, it's to help him remember which of his hands is the right. A deluge of similar mock-trivia has become the national pastime ever since Estrada took over the highest post in the Philippines. And the President has little choice but to take these figments of mischievous public imagination gamely. The real reason for the famous wristband that has accompanied Estrada through the years of his political career—as mayor, senator, vice-president and now the president of the Philippines—is to conceal a keloid which the President had received from a sword during a movie scene rehearsal.
