I was looking thru a site called Quora today when I came to the question: "Who was the first woman to go to space and return to Earth?"
Naturally, it was 'Alice Kramden' and I thought of myself as very clever to think of it..., until I realized that I might be dating myself..., and a lot of people (most?) would not get it!
If you don't know the answer look it up on Google.
