SEK accidentally cracks the control panel on the Smart Lectern trying to turn on the lights after playing a clip. He calls the tech people. Afraid that The Library will somehow blame him for this, SEK asks his class not to tell on him. TECH PERSON arrives.
TECH PERSON: What happened here?
SEK: Don't know. Was like that when I got here.
TECH PERSON: (points at the clip still displayed on the wall) How'd that get up there then?
SEK: It was working at first.
TECH PERSON: At first? Before you got here?
TECH PERSON looks up from behind the Smart Lectern and eyeballs SEK'S STUDENTS.
SEK'S STUDENTS: (SIMULTANEOUSLY BURST INTO LAUGHTER)
SEK: (to no one and everyone) Almost done?
SEK'S STUDENTS: (WEEPING UNCONTROLLABLY)
TECH PERSON: (turning on the lights) All done.
SEK: Thank you. Now as for you lot ...
