Overheard: Wite-Out™

Astronomy 210L, spring semester 2013
Cuesta College, San Luis Obispo, CA

(Overheard as students are working on their astronomy laboratory worksheets.)

Student: "P-dog--do you have any Wite-Out™?"

Instructor: (Making crossing-out motions.) "Can't you use 'black-out?'" (Looks around the instructor work station.) "Besides, I can't have any Wite-Out™ lying around the classroom--it's a controlled substance."
