When I was a kid our house had a bean bag chair which our (large) dog had claimed. One day while we had family over I was sitting in the chair since we had otherwise ran out and our dog was obviously displeased.

He walked over to me and stared at me for a few minutes. After telling him “no” he walked off and returned with a bone which he promptly dropped on my head. I got up, he layed down and no one ever sat in his chair again.
