Two observations about the geography answers:
1. Nobody - and I mean nobody - is as bad at the geography rounds as the celebrities.
I don't know why that is, because you would have thought that they'd be well-travelled, etc, and know a thing or two about other parts of the world but some of them are appalling.
Tahiti is not a country, guys, any more than the Isle of Wight is a country.
2. Nobody will ever cock-up a geography question as the contestant whose answer for a country in Africa with a repeated vowel in its name (ie, at least two As, two Es, two Is, two Os and/or two Us) answered... Goa.
Wrong on three counts: it doesn't have a repeated vowel, it's not a country and it's not even in Africa.
The thing is, that person wasn't even going first. I think they were the third person to answer so when Richard went over the first couple of answers ("Yep, Nigeria, two Is there") he should have been clued up as to what was needed even if he hadn't listened properly when the round began.
