Catbert says, "Your classmates will be a glass hammer and a bag of nothing"
Now re-read this statement "Your classmates will be a glass, hammer and a bag of nothing"
Yes, it is possible that there might be a mistake. It might be the same one that you pointed out or maybe someone just missed a "," or perhaps Catbert is testing our IQ. We will never know the truth!
I actually think mm1145 had a very good point. It's just hard to take criticisms seriously when the critic is unable to correct or even see the same faults in himself. I mean, would anyone really take grooming criticism from Wally no matter how correct he might be? Management advice from PHB? Dating lessons from Dilbert?
Re: "loblong" and the glass hammer thing...
I think the little dance between loblong and the responder were as funny as the strip today, at least the third panel of the strip. I thought Scott dropped the ball a little on the punch line for this strip. The setup was great but the final pane disappointing. And, oh, by the way, what about that real-hammer-looking hammer? The illiterate writer had a point, you know.
