Mother-in-Law

A man's house is on fire. He runs out of the house with his son and tells him to wait outside. Then he runs back in and gets his daughter and brings her outside. Then his wife. Then the dog. Then he goes back in a couple of times without bringing out anybody.

So a fireman asks him, "Why are you going back in there?"

The man replies, "I'm turning over my mother-in-law."
