Star in a car was someone I'd never heard of, why not get someone that has some sort of interest in cars at least, and a proper interview!
How can you not have heard of John Bishop. He is really rather funny - well as comedy is subjective, I and quite a few people I know find him funny.
He's been on Mock the Week, Live at the Apollo, etc and etc.
You need to stop having a life and sit yourself down in front of the TV for a good few hours. Get yourself some popular culture education! 
I thought last night's TG was fine. Very amusing with some good cars. What more do you need?
Haters gonna hate, lol.
No, never herd of John Bishop, I've seen Mock the Week quite a few times, but never seen the legend that is John Bishop on it, and live at the Apollo, is that that show full of 2nd rate so called comedians? I suspect he was only on TG because the BBC will be trying to push something with him in, over the next few weeks!
I think that TG is good, but has backed itself into a corner, as presenters, I still enjoy all three of them, I just find the concept of the show, is now dull and boring, and they need to move onto something fresh
