Yesterday I accidentally learned that you can reposition the closed captions on YouTube videos. I waa at the Smartboard talking about how the cursor and my finger were a couple of inches apart, and I accidentally dragged the captions of a YouTube video that we were watching.
A multimeter in amp mode acts the same as a regular wire. So you can use the probes as a means to generate a signal. If there is a god, and it is an engineer, then I am probably going to hell for this.
