The Obvious, Child

Take two brainless tubolards and stick em on an escalator side by side and have them just stand there in a perfect demonstration of the techniques they used to become tubolards in the first place. It used to be that when I found myself impeded behind these self absorbed and inconsiderate pieces of human flotsam, I would practice my zen patience mode.
Now I just charge past them with a loud and sarcastic "Excuse me!" hoping they will fall and break their necks and die.

Zen can really make you waste a lot of time.

Another big time waster is those single slotted screws that the screwdriver always manages to slip off, epecially if you are using a power drill with a bit to drive the screw. Single slotted screws should not even exist, they should be removed from the market and the people who make and distribute them should be dragged from their homes in the middle of the night and screwed to death in front of their families. Nothing lower than a cross head or Phillips screw should be on the market...square head or Roberts screws are better. Oh yeah, and I have a special hatred for the jerks who design a fixture of any sort that requires screws and different types of screws are required to assemble it forcing you to constantly change drivers or bits. What are those morons thinking? What is their damn point? Its got to be intentional. I hate them with a passion.
