Is Mr. Castor just... ad libbing?

Ever have one of those nightmares where it's your time to talk and everybody's looking at you, but you haven't prepared anything?

I've had that nightmare a million times, but never once where the amount of time I had to tread water and ad lib and fail and flail was **four hours**.

Now I'm worried that the next time I have this nightmare, I'm going to say things like "off the top of my head I can't remember" and "whatever it was, I'm not sure". That would be an even worse nightmare than my usual.

In my recurring “I’m not prepared and yet I’m talking anyway” nightmare, if I got to a point where I said “Nebraska is quite the judicial thinking place,” I think that’s the time I would wake up yelling and sweating.
