Little Johnny...

Students wanted to bring the teacher Christmas presents. She said it would be fine, but the presents have to be associated with what parents did for a loving (to be educational for other students). Billy handed the teacher a present. She said, your dad works at the record store. I'm guessing it's a CD. She was correct. Johnny brought his present up. It was a shabbily wrapped box. She shook it hard, trying to guess what was inside. Suddently the corner of the box got wet. Knowing Johnny's dad worked at the liquer store, she was afraid it was alcohol. She touched her finger to the wet spot and tasted it. Johnny!! You didn't bring liquer to school did you? No ma'am, said Johnny.

Spoiler:

It's a puppy!! Dad got fired and works at the dog pound now.
