I am trying to identify a real movie or TV scene.
The scene takes place in a classroom, with the teacher sitting in a wheelchair. A student comes in with a Coke, and the teacher says something like, “Coke is not allowed here.”
The kid says, “This isn’t Coke; it’s Seven Up.”
The disabled teacher then says that drinks are not allowed in the classroom.
The kid responds with something like, “What, hmm?” as if to say, “What are you going to do?”
The professor approaches the kid in his wheelchair to confront him in a threatening way, and the kid says, “Do not approach me.”
