If I'm feeling like being productive, switch to another instance of my dev environment working on a different branch of the source code, in which I'm working on a different problem entirely. It's just two (or more) branches being developed on the same machine in two instance sets of my dev env, side by side. Usually, though, I do that thing where you open your mouth in different shapes and smack the sides of your face to make noises. I'm trying to play "The Entertainer".
