Non-Standard Worms

Earworms are all well and good, but I have other kinds of worms, too. Like when I see a reference to an actor and think, I gotta watch that movie NOW! Or like when I get it in my head that I need a Diet Coke or some potato chips and I'm gonna be distracted about it for a long time (well, for the next hour at work). Here's the place to register your non-standard worms. I'll stick with the torment unit of measure.
