This was a request from my roommate, who works in a call centre. He's been working very long hours lately, burdened with training a new group of interviewers on the most critical project at the company. A project so critical it offers a $2-per-hour bonus just for working on it.
So naturally the little bastards are goofing off.
Or, alternatively, you could see it as sweet revenge against all those people that call you during the dinner hour. Take your pick.
