Vardibidian recently pointed to a Ronnie Corbett sketch involving double meanings of terms like “Blackberry.”
I enjoyed the sketch; fun verbal comedy. And I was pleased, because I often see that kind of thing (dual interpretation of tech terms) done in ways that I don't find funny at all.
But it wasn't until now that I learned that it goes back to an earlier tradition of Two Ronnies sketches: in particular, the 1976 four candles/fork handles sketch, in which a shopkeeper and customer repeatedly misunderstand each other.
The older one includes a couple of jokes I don't get—presumably based on British and/or 1970s terminology—but I did laugh out loud a couple of times, so I figured it was worth pointing y'all to it.
