In the office where I work, there's a constant battle between our technical support director and customer service personnel over the room temperature, which is usually too low.
The frustrated director, trying to get us to understand his position, announced one afternoon, "We need to keep the temperature below seventy-five degrees or the computers will overheat."
Thinking this was just another excuse, one of my shivering colleagues retorted, "Yeah, right. So, how did they keep the computers from overheating before there was air conditioning?"
