This question has been bugging me also, I asked friend/family and nobody knew.........so is the fourth a taxi driver? it sounds awfull but I'v been waiting for fizz's baby to die because that was the only one I could think of.
The producer said in one interview that the play on words of the tag line of 'four funerals and a wedding' was too good to miss out on but because they only had three of the cast to get rid of they included the taxi driver too.
