'What is sauerkraut, anyway? Is it like it's own vegetable?' -- Girl working at the Swiss Chalet. Where they have sauerkraut.
Unfortunately I didn't hear Tom's reaction.
My point--or not really, but I'll make one up just now--is that she could still be smarter and more general-knowledgeable than you or me. Everyone has missing bits of general knowledge, and sauerkraut is hardly the most significant any of us have. Last week I was surprised to discover that American College football isn't played only on Sundays, but also on Saturdays. (Oh, I'm sure I knew that. They kick good TV off for football every day of the week, but I don't really think about football.)
I'm too lazy to go on and on about it.
