"Well Done!" joke

A man's house is on fire. No help is in sight so he takes matters into his own hands.

He runs out of the house with his son and tells him to wait outside.
Then he runs back in and gets is daughter and brings her ouside.
Then his wife. Then the dog. Then the cat.

Then he goes back in "3 more times" without bringing out anybody or anything.

So a bystander is curious and asks him, "Why do you keep going back into your burning house and not coming out with anything?"

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