I finally got one for this thread.
One thing really ticks me off is when one of my favorite web sites does an upgrade / design change and the main and plain navigation style changes. For example the links used to open their own windows and all you had to do was close them down and your back to the main page now instead it closes the site/browser down because you should have used the back button. That gets me for weeks till I break my formed habits and has me doing the Homer simpson Dooooolt everytime.
:lol: Okay then one let me go with one of mine, "the people in rush hour or anytime for that matter who decide to stop in the acceleration lane to wait for a break to merge into traffic onto the freeway/highway" .
