oh...and Dilbert doesn't need a guardian robot. He has a guardian dog. It may be a sort of "don't mess with my doormat" kind of guardianship, but I'd give a lot for the protection Dogbert has given Dilbert.
"Rhymes with witch..." Exactly! Dilbert's retort may have been blunt, but what do you expect from Dilbert? He is not exactly a master of subtlety. But just read her ego centric reply to his generic-all-purpose apology/excuse for not fulfilling her "ten minute request".The women in Dilbert are scary, but so are the men. I hope the comments here (all of them together) have enabled those who didn't get the joke to understand. But of course, it's only funny if you get it the first time.
