when i was married to my first wife, she was korean, she had a couple of female pekinese which she spayed, anyway when i would call them they would come screaming around the couch as fast as they could run, and real tight turn, so i put a small box by the couch and when they were in the kitchen i called them, they came screaming around the couch and bam, right into the box, the daughter who was a little smaller was trailing and she ran into the back end of her mother. neither one was hurt or even scared, they just looked at me like why would you do that. it was funny watching that small train wreck. neither one came around the couch like that again which is what i wanted. they were going so fast and such a tight turn they was beginning to tear up the carpet. i laughed till i almost puked.
