LOL!

I've been laughing for a week now...
I went on line last weekend to check the movies playing in town, and read a few of the movie descriptions...
One movie had a warning: extreme violence, sexual situations and smoking...

Then there were the three documentaries I watched subsequently on TV about our space program, and the history of the sspace program --- non stop smoking by the sharpest minds of their generation.
