Newbie installer gags

The best one i've got taken on was when I was hooking up locks on a 2000ish gmc pick up and the "guy who had been there the longest" was watching me quietly through the passanger rear window and he just happened to have the factory keyless remote on him... and he could see my every move so when he saw me connect the lock wires he started setting the remote into lock and unlock... then I paused to see what was happening and he stopped... Once I would touch the wire with my finger he did it again... He had me going for almost 5 mins I started disconnecting all my connections getting the test light probing until I could hear him giggling I was like "Ohhhhh, its on...."

So a few weeks later my boss brings out a few slices of cheesecake and leaves it on my bench and asks me to share it with the other guys and also leaves his chicken ceasar salad beside the cheesecake... So the guy that took me with the locks come over and is like "Mmmm salad i'm starving!" so he asks who the salads for and I just reply "I Think he (Our Boss)left it for us, he said eat the cheesecake up" so he starts pouring salad dressing all over the salad and goes to town cause its like 1:00 and he hasn't eaten yet and he's just munching away when all the sudden I start laughing slightly, then he thinks for a min, but continues to eat the chicken ceasar salad then just when he has a mouthful of the vegitation sticking out of his face in walks our boss looking around "Ok, did I leave my salad out here???" The guy about pounded me but I got the last laugh... Needless to say I had to buy my boss lunch the next day

The best installer gag I have ever played was onthis one install I had an amp rack that was to come out of the trunk to the rear and display....It was on a pnuematic cylander that was hooked to the Air Bag system that was already in the car....The way the rack worked was it was hinged at the rear of the car and the piston was toward the front of the spare tire well....I hadnt tweeked the valves for the cylanders yet so the piston was tossing the rack up at tremendous speed...

one of the new guys was going to do a fill pannel on the side of the amp rack..And he was putting his tools in the trunk so he could get to work (pencil and some carboard)....I had the remote which operated the cylander and when he would turn his back I was hitting the button and tossing his stuff out at him...Like a catapult...It was noisy in the back so he couldnt hear the air piston actuating...It took him like 10mins to figure out what was going on...He had no idea I had the piston on remote...

He just kept checking the wiring going to the valves for the piston and was going nuts...He would test it by placing the paper and pencil back on the amp rack...I again would wait for him to turn around to actuate..We all were standing at the door laughing our asses off...Never had so much fun with air piston...

Making the World A Louder Place

I've wired a mercury switch, 9volt battery and a siren to lid of their tool box so when they open their tool box the siren goes off. 

Some times its the reverse, Or i would just ask stupid questions just to annoy the installer or to see if he's really hooking me up.
