I like that quote. I've never heard that before.
Those old black and white comedy skits were funny. I have a mind to show them to my grandchildren. I haven't watched many since I've been an adult, but I still get a kick out of The Three Stooges and Laurel and Hardy. They were true comedians. Funny without being dirty, and you could laugh for hours. As you say, laughing at life.
We spent many happy hours watching short films, as you mention good clean fun. It could be fun sharing with your grandchildren, at the same time bringing out the child in you.
