"Hey Mom, I was sorta, like, gonna assassinate the president and stuff, and, you know, it's like... oops, I guess I messed up, huh?"
There was a French (of course) film in the mid 1970's - I think it was called "Le Weekend."
It was about these spoiled rotten rich French students who joined some kind of Weatherman-like organization and ended up assassinating an Ambassador or high politico.
The film is told partly through flashbacks and partly through narrative by one of the students. In the last scene, after they show the flashback of them killing Mr. Big, they go to her recounting this story.
The person she is talking to, rather in shock at the events, says, "So . . . what happened next?"
She shrugged and said something like, "Oh, we went back to school. Classes were starting."
