I might say “Here’s Johnny” and half the folk under 30 would have no idea, and half the ones who recognize it would only know 1 of the 2 references and couldn’t tell from the context which of the 2 I was actually referencing.
Anyway, I suspect what we have here is a failure to communicate…
One from Rik Mayall or Ade Edmundson cant remember which, I use it a lot -
“Never ever bloody anything ever”
“Nobody wins unless everybody wins” is another.
" Stay out of trouble you crazy kids" from Pulp Fiction.
The greatest line in history - Churchills “We shall never surrender” is up there. and Bill Clintons “I did not have sex with that woman” and finally - “If the glove dont fit you must acquit” from the OJ Simpson trial, all contenders.
