There is a specialised program I use at work which crashes nearly 70% of the time when one tries to print. These crashes, of course, always occur at wildly, insanely inopportune moments, such as when a patient's discharge transportation has already arrived and you are trying to get a signature form with all his follow up instructions ready.
Everyone in the department has superstitions about how to keep the program from crashing - counting to a certain number before hitting Print, tapping the screen a certain number of times, clicking on an empty section of task bar...
I scoff. Ridiculous. Those things can't possibly have any effect on the program. Unscientific. I have found, however, that loudly singing "Yellow Submarine" works quite well.
My coworkers are not as entertained as I thought they might be.
