Over sandwiches Lola asked me thoughtfully, "What is the fourth dimension?"  After I finished chewing, I called the Sober Husband in.  He has a Ph.D. in physics, after all, and I, moronically enough, was not sure about what the fourth dimension was.  This was the right thing to do, as the Sober Husband lit up when Lola repeated her question and said, "Ah!  Now, what is a dimension?"

Later I had my moment in the sun.  "What is the Antichrist?" Iris asked her father.  He was blank, and I intervened.  "Leave this one to me,"  I said.  I didn't have a born-again Christian childhood for nothing.
