Patrick Cauldwell and I had lunch today and were talking about how funny it is when someone looks at code for hours trying to find a bug (or stray semi-colon) and the parallel was made with the Ninjas that The Tick couldn't see. They would hold sticks in to disguise themselves as shrubbery. As soon as they did this, they were immediately invisible to The Tick. As soon as they moved the sticks, well, you get the idea.
I wonder what makes folks not see the Code that's right in front of them?
