Firstly, Andrew thinks his jokes are funny and some are not even timely and most in poor taste. He also thinks he's a linguist and pronounces words with accents - which throws me - sitting at home - imagine what it does to the contestants.
Secondly, it seems poor form that the contestants need to not only wait for the entire question be read out, but also, for their name to be called. The chasers don't even have to wait for the entire question and can jump in with an answer at any time. That's not fair to the contestants who have worked so hard to get a bank balance.
