Only in college VII

A friend needed something specific for a science project.  Her family ordered the item and sent it to her at college.  When she picked up her family's package at the dorm's front desk, the students sorting mail looked at her oddly.  This reaction puzzled her, but then, she looked at the package.  The box was stamped, "HUMAN SKULL," and one of her parents had helpfully written, "SENT FROM HOME," next to it.
