So I was talking to a friend of mine about how we used to play lab pranks back in the day when I used to be known as Canz, and I used to be a bit of a motherfucker back then. The best prank we ever played together was on a technician from another lab named Carl. This prank was epic and honestly we probably should have been fired for what happened to Carl and the darkroom. But first, why play a prank on Carl? Glad you asked, Carl was a bit of a prankster himself and would set up timers all over the place to go off in a coordinated sequential manner. And I mean he hid them everywhere, I shit you not I had to get a ladder to get up into our 15 foot vaulted ceiling to get one down. He would also rewire your computer setup, good luck printing shit. After getting pranked by Carl, the departmental jokester, a couple of times it was time he paid the piper.
So let's get to the organizing of the prank. We knew that day that Frank was going to have to go into the dark room to process expose and develop a western blot. This was going to be the site of the prank. So we went around to all the other labs and warned them to stay the hell away from the dark room. I went to a store that rhymed with Smadio Smack and purchased five 130 db personal safety alarms, the ones that have the pull pins to activate, and grabbed some fishing line from my apartment before returning to work.
We wired the alarms in place, I'll get to the details of this later and turned off the lights. And then we just waited, along with everyone else on the floor who knew what was about to happen. I grabbed one of those wooden triangle blocks that you use to hold doors open and traversed the hallway as Carl was walking to the dark room. As soon as he went into the revolving door, I took off like a fucking gazelle for the door and jammed the wedge in so the door couldn't open.
Poor Carl, as he stepped out of the revolving door, his foot kicked the first trip wire, pulling the pin out of what is ostensibly an alarm that a college coed would carry on their person at night walking home from the library. Well in the small confined spaces of the darkroom, pulling the pin activated a 130 db alarm that is almost as loud as a plane taking off. The only way to shut off the alarm is to put the pin back into the alarm, not easy in the dark, especially when the light switch is all the way across the room.
I imagine Carl tried to make his way across the room to the light switch but he activated the four alarms which made the room deafening. By the time he got the lights on and saw all the pins, Carl was left with the choice of taking his hands from his ears to put the pins back in leaving him vulnerable to the alarm or just run back out of the darkroom. Carl chose the running option. Unfortunately the little door jam was still in place, Carl about ripped the revolving door off his frame trying to get out, while I'm trying to get the fucking door jam out to let him out.
At this point, I go in with some ear plugs and put all the pins back in and come back out of the darkroom to find Carl laying on the ground holding his ears and tears running down his face. Luckily Carl suffered no permanent hearing damage, but his hearing was shot for the rest of the day.
Best prank ever...in the lab.
