Bizarre Turn Signal "Clicking" Problem

Since fixing a few of the more distressing problem with my car (thanks to the help of this forum), I've enjoyed driving it lately, virtually problem free...that is until I used the turned signal to signal a lane change, and after letting go of the switch, heard the "clicking" noise of the signal continue at various speeds even after the switch was off.

I drove for a solid five minutes and the signal noise was still ticking off to its own drum. I turned the car on and off and it didn't do any good. After five minutes, it starts to settle down, but any time I use my turn signal the problem starts up again.

It's crazy. Does this sound like a short somewhere in my electrical system, or could it be something as simple as a fuse. I love this car, but damn these are some weird problems.
