You just hadda say that, didn't you, MB? You just hadda.
One of my favorite episodes was "Visit to a Hostile Planet." The Robinson return to Earth, happy as clams they made it home, not realizing they had passed through a time warp and landed in the upper peninsula Michigan in 1947. The explore the lumber yard they landed in and Maureen and daughters Judy and Penny go into an office and see an old-fashioned telephone. Maureen is totally perplexed on how to use it to communicate with someone. That's not so far off. Believe it or not, I've had students ask if they could use the desk phone (all land-lines) with a receiver and push buttons. I tell them yes. They look at me, perplexed, and ask: "What do I do?"
