It is much easier for time to pass unnoticed when you have music playing than when you have the television on. Especially if you're coding. When the TV is on, particularly if you use something like a TiVo to view your television, you are very aware of when each half hour or hour or two hour block of time has passed, since your show has just finished. Whereas it's quite simple for several songs to pass and you not realize it, it's all just faded into the background noise.
(This tidbit brought on by the fact that the last three hours passed without me noticing them.)
So, I'm watching Third Watch, and one of the firemen is giving a tour of the station to a bunch of elementary school kids (like, 2nd - 3rd graders). A bored paramedic is wandering around upstairs in the firehouse, looking for something to do. He notices the pole (you know, the pole), and leaps on it... then gets stuck. He tries to wiggle back onto the ledge he jumped from, and falls down through the opening in the floor, landing on his back. His vision blurs, and as he's shaking his head, the children from the field trip all crowd around him. As the closest child approaches him, he says, "I thought I was dead, and... that my own personal hell consisted of evil little midgets with sticky fingers, missing teeth, and pigtails... Children." And then he started screaming.
See, that's how I feel about children, most days. (Yes, yes. Keep your hate mail to yourself.)
