Costly Mistakes

So yesterday, our teacher announced the introduction of a new learning device.

The nickel can.

Starting Monday, every mistake we make in language that we should have gotten right will cost us five cents.

The can isn't new...she used it for the last class too. It has a sign on the side. It says, in Estonian:

[Name Redacted]'s New Tooth.

But she said she made enough off of the last class for the new tooth, so now she wants a new cellphone.

She fixed the sign accordingly.

I'm planning to pick up some rolls of nickels.
