A grandmother and a child were driving down the road.

They came across railroad tracks, and the little girl said, "Look, grandma, choo-choo."

The grandma said, "No, the proper name is train."

As they continued driving, they saw a farm.

The little girl said, "Look, grandma, moo-moo."

"No, the proper name is cow," the grandma said.

The next day, they went to the library, where the little girl picked up a book and said, "Look, grandma, Winnie the Shit!"
