I went speed dating a few months ago, and the quality of birds was OK. Yes out of twenty birds, about 5 were absolute munters, 3 were dogs, 2 were mekons, one looked like Noel Edmonds and one was Asian. Therefore 8 were passable. Of those 4 or 5 expressed an interest in moi, of which I matched two.
I knocked one of the head immediately when I realised she chose 17 of the men involved and assumed she was just desperate to be a mother.
The other one, who was stunningly beautiful and a high flying legal exec in the city, didn't really go anywhere. A few emails and we never spoke again.
But overall I would say she was sane and no doubt would be good quality bird material.
