I'm joking, but it hits a little close to home because all of us have done that before. You're at the end of your rope and just need this thing to fucking work and you'll deal with the "why" later. For now, x = x works dammit, and it doesn't matter why. Meanwhile the console is filling up with all of your variables being printed out because you couldn't figure out where the value of x was being corrupted.

The next morning you switch to functional programming and forget that day ever existed.
