Does your wife consider it a mystery too?
Yes, she does. She came home that day, and said, "How did you manage to get rid of that stump?"
Yup, she's in on the conspiracy too.

Who cut down the tree?
I did, some time before. But I didn't dig up that stump.
Yeah, and you did not kill the deputy, we've heard that one before.
Tell me, if a tree stump mysteriously disappears and there's no one around to watch, does it produce a puff of smoke?
