As the weekend approaches, Hart gets a special, paying assignment to index Kingsfield's new book of essays, due Monday - an impossibly difficult deadline. On top of that, his employer Ernie asks him to manage the tavern while he's away for the weekend. Meanwhile, Bell becomes obsessed with his goofy picture on Kingsfield's seating chart, believing that's why he always gets called on first in each class. Bell sets about getting his picture changed. When Kingsfield's secretary declines to change it without his approval, Bell arrives on the hair-brained scheme to break into Kingsfield's office and change it. While everything possible is going wrong at Ernie's and the index is still looming large, Hart inexplicably agrees to accompany Bell in this ill-fated mission, ending up trapped in a closet over the weekend.
