Dilbert stands behind a man with an eye patch who is working on his computer. The man says, "My theory is that a computer interface should hurt the user." The man continues, "So I designed some new sounds into our product. We've got 'sound of puking,' 'fingernails on blackboard' and 'bird hitting window.'" Dilbert looks ill. The man continues, "But suppose the user does something WRONG. Then we have the sound of a puking bird hitting a blackboard." Dilbert falls down.
