Similar experience here. My old roommate's name is Khanh and he found a clip of William Shatner yelling "Khan" from a Star Trek movie that he put on his voice mail and as start up sound for his PC. Every so often he would leave his speakers turned up and in the middle of the night his computer would restart due to a windows update. I'd just hear William Shatner yell KKKKHHHHHAAAANNNN randomly in the middle of the night.
