Bank officer: Good morning Money Kumar! What brings you here today?

Money Kumar: We want to exchange a few soiled notes.
Bank officer: Sure, give them to me.

Money Kumar gives him soiled notes and gets fresh ones back. But there's a small problem.

Bank officer: I'm afraid this note is mutilated. It can be exchanged only at our main branch.

Children: Mutilated? What's that?
