Ive been meaning to come on this thread since I first spotted that David is a natural comedian, without knowing it, and to my mind that is what is so hilarious. As someone has already said, he is very much like Keith Lemon, but the real thing. He must be kept in at all costs. This show badly needs a laugh and David is the only really funny hm there. I love his humility, he knows how lucky he is (or unlucky!) to have succeeded in the auditions and is enjoying every moment of his time in the house.
I'd like David to stay for as long as possible as he is very entertaining. As ever, it is up to the producers how they play it, let's hope they come up with some good tasks that allow the hms to shine.
