Anal Retentiveness: In our quest to not spend money we didn't have, we were pretty anal-rententive/uptight about not tearing wrapping paper. Typically we were each handed a steak-knife before opening gifts, to avoid any unnecessary ripping/tearing. (In recent years, I've definitely gotten my fair share of grief for this one.)
Paper: Because of the aforementioned aversion to tearing, there was wrapping paper older than me. And, like the aforementioned triangular shaped hospital freebie formula sample box, the same rolling commentary about what all had been wrapped in that paper ensued.
