Much was always made of Jack & Vera in Corronation Street, and latterly Norris & whoever.
I can't ever see any decent humour in Eastenders, not that I watch it these days.
But my favourites are Viv & Bob in Emmerdale.
I love her - she's just so over the top the way she dresses, her need to know everything that goes on and her sheer hypocrisy.
And Bob - his surname is Hope - who is forever trying to please his wife.
