Why didn't Hyacinth just change the surname from BUCKET to BOUQUET?
It is simple enough in the UK to change your entire name by deed poll, so if Hyacinth was so frustrated by people refusing to pronounce Bucket as she wanted it, Bouquet, then surely that was the answer?
Maybe Hyacinth has to keep the family name Bucket because of some reason, and it does generate laughs from the audience in the show. The problem is, the same joke is repeated over and over again every episode and this aspect of the show, aside from many, many repeating jokes per episode, is why this is a shitty comedy along the lines of 'Allo, 'Allo, another shitty comedy that's way past its sell-by date.
