Dave the VP of Sales strolled into the development department. 

“Wow. It’s as quiet as the grave in here!” He announced to the room in his loudest look-at-me-I’m-a-salesman voice. 

“Don’t you people ever let your hair down and get chatty?”

All the developers looked at him with quiet contempt.

He laughed, blithely oblivious to their stink eyes.

He strolled across the floor and guffawed again before flouncing out of the room and into the research VP’s office. The door closed behind him. The room sighed, and got back to the important work, having lost 400 minutes of work between them in under one.

“Jerk” was their considered opinion.
