There are multiple cases of movie or TV show students who are attending an exam and are too late to turn in, but then ask the teacher "do you know who I am" at their desk. Then when the teacher says "I have no idea", they mix in their exam with the pile of completed exams and then walk away. 2 examples of this: https://www.youtube.com/watch?v=_CqgnZhb--Q and https://www.reddit.com/r/BollywoodRealism/comments/hzeu2u/i_so_wish_this_was_how_it_worke/
Now, I know that these are just fictional scenes from comedy movies, but if a student were to try and pull a stunt like this during a real exam, what are ways to deal with this and/or avoid this problem to begin with?
