Just a short anecdote from Christmas vacation...
My mom and I return to her house after an afternoon/evening of shopping before Christmas. My grandmother - 86-1/2 years old, bless her - was watching television. She's a little hard of hearing and the volume was down, so I guess she was mostly interested in what was going on visually. We walked in, said hello, put things down, then I noticed what was on TV.
My granny was watching a Cheech & Chong movie. If memory serves, it was "Up In Smoke".
Wow.
