....has just suggested to someone with a software problem that she take her computer apart, and spray the contents with WD-40.

The same fathead keeps referring to "departments" on his own computer. At first I thought he meant partitions, but closer examination revealed that he means different browsers.

My (very controlled response) was "you mean browsers". His reply was "I don't care what you call them...."

I often wonder how he would fare with gibbering nonsense like that on an IT-specific forum, or indeed a sports-specific forum such as the one I watch, where if they think you don't know what you're talking about, at their level, you are likely to get mercilessly hammered into oblivion.
