Actually my own computer..
I was a technician, who also did a little coding if we needed a particularly utility for some purpose. One day, I was working on one such utility, and had my c++ IDE open (Borland - None of this visual studio crap). The utility was compiling correctly, but some values were not getting passed internally, which was causing it to fail when run.
After spending hours looking for the bug, and finding nothing, I leaned toward the computer. I asked it if it wanted to be thrown out the window (pointing to the window for dramatic effect). Oddly it worked after that.
I had that computer for years (actually until I needed to replace it with an iMac), and every time it went wrong, I just whispered "You know where the window is, don't you?" and it would start working.
