This is yet another in a series of math-related cartoons I did in high school. I didn't really like math (except for trigonometry), so these cartoons were a coping mechanism.
In this one, the sarcasm is ever so subtle. Since I felt so little attachment to my calculus book (I who knew the value of its contents), I thought it would be ironic to depict babies having a strong attachment to it (they who know nothing of its contents). Get it?! No? That's okay. It wasn't that funny to start with.
