Logic Lesson

A Fourth-grade teacher was giving a lesson and logic in class one day.

"Here's the situation" she said." A man is standing up in a boat in the middle of a river, fishing. He loses his balance, falls in,and begin splashing around and yelling for help. His wife hears the commotion, and knowing he can't swim, runs down to the bank. Why do you think she ran to the bank?"

A girl raises her hand and asks innocently "to draw out all of the money?"
