<p>I just found this LOL. In the late 80's my friend and I ran a electronic repair shop with about 4 people. We would wait for someone to go into the bathroom, string together heavy test leads, have a pre-sharpened a pencil at both ends, and slid this under the door. We had a huge rack-mounted &quot;power supply of doom&quot;. This thing could pump out many amps current limited. The pencil ignited and filled the bathroom with smoke. Was a hilarious prank that happened all the time. Made use almost afraid to go in there. Another prank: when repairing an older crt televisions, make a loud clap behind the person doing the repair. You never get used to the sound. Just like that of an exploding capacitor.</p>
