While we all enjoyed the galavanting of Indiana Jones throughout his four movies, there's one key issue which is barely touched upon throughout: he's a fully employed college professor. It'd be naive to think that Jones only went on four quests in his lifetime, given his fondness of stealing things for museums, so it's fair to say that he's absent from the classroom for vast periods of the academic year. As such, the students abandoned in the lecture hall are left to fend for themselves in order to achieve a good grade. The frustration of their neglected state can be seen in the very first Indy movie, where they swarm his office as he attempts to gather his things to head on yet another adventure. They are literally screaming at him, and one even attempts to coerce him into staying by declaring her love for him via the medium of eyelids, such is the desperation.
