My parents have this story they've told for my entire life. The story is short. It is about the funniest movie ever made (according to them). My mother likes to tell it every few months. The short version is:
My parents watched the funniest movie they had ever seen. It was a cowboy comedy. The bad guy wears black, the good guy wears white. It's full of every cliche you can think of. They never stopped laughing. They thought it was Blazing Saddles, but it wasn't. Now they can't figure out what movie it was.
This past Sunday, my mother made an odd comment which was obviously a quote of some sort. I asked, she said it was from the movie, after the short version of the story. And, once again, lamented on not knowing the name of the movie and so being unable to watch it again.
Fortunately, this is the future. We have a global database of every bit of information that survived into the 21st century (including a heck of a lot of misinformation) which is searchable by everybody at all times; provided you have a smart phone and data plan.
Google to the rescue! "You put that violin up under your chin where it belongs". Which was the mis-quote of the actual line (Google figured it out anyway), "you just tuck it up under your chin like a fiddle's 'sposed to be played". And IMDB provided the rest.
I still haven't seen the movie. But now I can find it and let my mother watch what she believes is the funniest movie ever made.
