When I have some tedious task that I can't put off any longer, I can't do it in silence. I'm normally not the type of person who has to have the television or radio on all the time. I like the silence as it helps me mentally focus. But when it's a task that I can pretty much do on autopilot, then my brain is going to want something to occupy it while the rest of me works from muscle memory. That's where my busy work programming comes in handy.
My current programming of choice is The Big Bang Theory. I've watched every episode and have the first four seasons on DVD. When I've got something annoying but necessary to do, I'll just pop in a disk, hit the play all, and get to work. Since I've already seen the episode, I'm not compelled to watch or really pay attention. It's like going on a long car trip with my brain in the back seat with a DVD of Finding Nemo. I get the job done without my brain interrupting every five minutes to ask me "Are you done yet?"
