You might not like it, but this is what peak bri'ish comedy looks like.
Or maybe both?
I forget the exact quote, but:
We specifically made something called “Harry Potter” and beat it to absolute death to show you we pronounce the letter ‘T’ in the majority of our accents.
Those truly tuned in to popular culture will indeed refer to The Sugarbabes, a UK Girl Group who presented a similar situation when all their original members were replaced one by one. This is the superior reference because eventually all the original members returned, elevating the situation to new levels of paradox.
(Peep Show, I would argue is some of the best recent comedy from us)
