Evan davis.
Why does he tell us things we already know?
On dragons den a would one of the hopefulls introduces themselves, and then they say 'I am here to seek a twenty thousand pound investment for 20% of my company'.
Then Ewan Davis on voice over says, 'Tom Brown is here to seek a tweothousand pound investmentfor a 20% stake in....'
I know, he just said that.
Then one of the dragons wil dclare themselves out, so Mtr Davis piopes up 'Duncan Banatine has just declared himself out...'
I know, he just said that.....

Sounds a bit like snooker comentating.
"He is lining up the red"
Yep, I can see that.
to be honest thats about as much snooker as I ever watch on tv, as the minute I see it as I am flicking through the channels I think "time to move on"
Which is the same thing I think about when I see dragons den actually....
Hmmmmm.
