I had an old disposible camera and a electro-zapping fly swatter lying around not doing much. I opened the camera and removed the capacitor. I wired said capacitor in-line with bug zapper once I removed the tennis-racket part. I screwed all back together, and looks like this (click on images for bigger versions):

Then, Mandy took a picture, dragging the shutter. This my little friend discharging on the metal screen in our den. The funny part was, some dude was sitting on the bus bench right outside of it. I wonder what he was thinking.
