Summer school?
I loved this movie's classroom scene, but it got me thinking.....
The action of this movie takes place in July-August 1969, right after the moon landing. Why would Indy, if he's about to retire, be teaching a summer school class? Aren't most summer school classes taught by younger faculty/grad students who haven't paid their dues yet? Maybe he volunteered because he was bored and depressed after breaking up with Marian?
I realize they wanted to have a classroom scene like all the other Indy movies, but I don't think the writers really thought this through.
