That fly's on your payroll, isn't it?

So this last weekend there was this big fly looping around the room.  John was standing next to the back door.

Me, "Open the door!"
John, "What?"
Me, "Can't you see that huge fly? Open the door!"
John, "It's not going to just fly out the door."
Me, "It's looping around the room and heading to the door.  Open it!"
John, "It's a fly, it doesn't know where...."
Me, "Open the door!"
John opened the door and the fly shot straight outside.

John, "That fly is an asshole."
