Jokes that, nowadays, need explaining

I have clear memories of getting back from a vacation and telling friends “It was great.You should be getting a postcard from me in a couple of days, you’ll see!”

My father used to buy a couple of professional strips of slides whenever we went in vacation and shoot one roll to show that we were actually in those places.

Damn. I miss slideshows.

Here is a joke that often requires explanation to those who would repeat it. “Take a long walk on a short pier”. Replace “on” with “off” and there’s no joke and no sense. Yet I hear it mangled so more often than not.

Look up ghosting with an HDR merge program. Still not workable in all situations but it’s a fun thing to play with.
