It does seem an odd choice to use the most odd-looking of The Young Ones to advertise your new bank account product. And yet, here’s a Vyvyan-like character in a commercial for Natwest.
I’m sure the use of the wrong hair was to avoid copyright issues.
This is the advert that is being referred to in this scene.
We’ve seen a version of Vyv in an advert on this site before of course. In case we’ve all forgotten, here he is with ‘Neil’ in a Friends Provident campaign. Sort of.
