I teach psychology courses at a community college.
I was teaching Intro Psych one quarter, and we were at the neuroscience portion of the course. One student spent every class either snapping her gum, texting, or staring off vacantly with ear buds in.
On exam day students were required to list the 4 lobes of the cerebral cortex and to write just one function of each lobe. It's an easy section of the test for most students. This one, however, could only come up with 1 lobe and its function.
Her answer: "Ear lobe - hearing."
Thank you, J!
