You Passed The Exam But Failed Security

Security Guard: “Hi. A student called us to report a suspicious person, but we can’t find the student or the suspicious person. Do you know anything about this?”

Coworker: “No one reported anything to me and I didn’t see anyone suspicious, either. Do you know what that suspicious person looks like?”

Security Guard: “Well, the student just said that the guy looked nervous. Did you see anyone like that?”

Coworker: “Every single student is suspicious, then. It’s exam period; they’re all nervous.”

Security Guard: “Oh, right. I didn’t think about that… Well, never mind, then.”
