This thread is cracking me up!!
We have a typewriter here in the office and one time I was using it a younger co-worker walked by and said "you know how to use that thing?". I about died.

Several years ago when I was working in child care we had a record playing during nap time. I asked one of the college students, who was working for his hours, to restart the record. He looked at me like this and said I don't know how.
