Based on a true story.
I was working at a pizza restaurant. One day, before the store was open, the morning crew (including myself) was just sitting at a table in the dining room, talking. At a lull in the conversation the jukebox started up, and I started singing along. As soon as I did everyone at the table jumped back in utter shock. They had no expectation whatsoever that this good-natured Mormon boy would start singing along to some Linkin Park.
