You know more about computers than the computing service personnel. Fake Plastic Trees is not just a Radiohead song. You've stopped at the non-stop stop sign. You know someone with two majors and five minors. Everyone plays guitar.
Nobody plays drums.
You don't know what building Warner Hall is. You've taken the class that gives CMU it's zip. You forget what sunlight is. You don't have time to go to class. There are more computers than students, staff, and faculty.
