That is so funny. Before I worked as a ProDom, I was in IT for a few years. I met former co-workers for lunch one day and they showed up with binders that had CBT on the cover. I nearly fell over. Did they know what I was doing for a living now? Were they playing a joke on me? As casually as could be mustered, I asked what the letters stood for. They looked as me as if I was nuts (No pun intended) and said, "Computer Based Training? Remember?" CBT can mean a great many things, it seems. lol.
