Wally: I did a huge amount of work this week. I created a matrix that compares all of our technology options. Boss: Can I see this alleged matrix? Wally: It's in my head. I didn't see a need to write it down. Boss: How would I know if you did it right? Wally: You're not an engineer, so you wouldn't know it was right even if you saw it. You tell me to "work smarter" but you get angry when I do. Boss: You're not allowed to do your work in your head! Wally: Which body part do you use?
