The people who removed the bees were the Backwards Beekeepers. The people who video taped, and commented behind the glass doors were new-bees (haha...) learning how to extract a hive carefully and take care of the animals. They got to take home the hive and try to keep them going. Taking home a twenty year hive is pretty unusual these days.
Then there were the bees in the furniture that were set out to clean up inside the house. The beeping you hear is the alarm system that needed fixing.
Then of course, there were the bees that lived in the garage for more then 20 years. The roof caved in afterwards. You can see the roof on other side had already discovered gravity.
