4PM This Dramatization of the Importance of Negative Numbers is the Grittiest Schoolhouse Rock Yet

CSR: Customer Service, this is Sheri*. May I have your account number please?
Customer: Why is my account negative?!
CSR: Well, if you give me your account number, I can look it up and go over your transactions with you.

Customer gives information, CSR verifies, and the conversation continues.

CSR: Well, ma'am, looks like your opening deposit on Tuesday was 25 dollars... And then you withdrew 40 dollars from the ATM on Friday.
Customer: And...?
CSR: Well, 25 dollars minus 40 dollars is negative 15 dollars.
Customer: I don't understand what you are trying to tell me.
