Re: I say it's plausible
This is what astonishes me most. The movie that gloriously enriched English culture with that sketch/joke (and many, many others) is now more than 45 years old and it's still as gloriously funny now as it was then.
I am eternally grateful for having grown up in that time, especially when an alternative group with Rowan Atkinson then also started to take the absolute mick out of them. Beautiful.
Apologies for the digression :).
