  I had this crazy prank caller few years back. He kept calling me in the middle of night or sometimes even during the day and kept moaning into the phone. Wah lao. Si beh pek chek that time, this whole prank call thing went on for about a year. Until I finally changed my number.
  
  Nb. And I still don't know who that fucker is.
