Greeting Card Quest

A little boy had been pawing over the stock of greeting cards at a stationery store.
After a few minutes the clerk became curious and asked, "Just what is it you're looking for, sonny? Birthday greeting? Message to a sick friend? Anniversary congratulations to your mom and dad?"
The boy shook his head, "No."
"Then what kind of card is it that you want?" asked the clerk.
The boy answered wistfully, "Got anything in the line of blank report cards?"
