I don't know when it started but I've noticed that I have a couple of stock lines or phrases I use whenever I have to write something and it doesn't matter what. If I'm testing a keyboard, making up data for a software test or testing a pen for the first time I always wind up writing the first few lines of "Good Times, Bad Times" by Led Zepplin. I may start with something else but I always end up writing it eventually. I know when I was much younger it used to be "It was a dark and stormy night. Suddenly a shot rang out!". Schulz was like a god to me when I was a kid.
So, what are your go to test phrases?
