I forgot my favorite guy drilled a grounding screw into his gas tank

how he didn't blow himself up I'll never know ...
I used to see that at CC all the fricking time. They'd get a head unit installed, and have a "friend" install an amp and use a damn stinger to put in a ground wire. Then they'd bring it back to us, and say we did it. Glad the computer always says what they paid for.
How about a kid that tried hooking up an amp but didn't know what the REM was on the amp, but he figured out that if you hook up the 12+ to it, the amp worked. But couldn't figure out why his battery was drained overnight.
Or A guy that is actually one of the best install guys I know, and does lots of custom work, but when he first started, he did a Semi truck. He fitted it with a CD Player, Amp for speakers and speakers. But he wrapped the wires around the steering column to keep them from hanging down. When the trucker left the lot, and started up the road, ALL of his electronics came ripping through his dash, No more CB, no more Radio, no more nothing. The ignition even went out. I wasn't working there at the time, but it was still funny.
