Wally: What happened to your head?
Dilbert: I've been banging it against a wall to reduce my frustration with my co-workers.
Wally: Is it working?
Dilbert: I think so because I don't remember your name.
Dilbert: We need to fix our user interface because half of our users can't figure it out.
Boss: Tell them to read the manual.
Dilbert: That's not how you fix a bad user interface.
Boss: Then why do manuals exist?
Dilbert: If you need me, I'll be banging my head against a wall.
Catbert: I need to talk to you about your bad attitude.
Dilbert: I'm surrounded by useless idiots, and I work in a fabric-covered box. How can I have a good attitude?
Catbert: Oh, good. I was hoping it would be something I couldn't fix.
