In terms of awkwardness, I'd say Gavin Henson looked seriously uncomfortable.
Anne Widdecombe is obviously the John Sergeant of the series, but I honestly think she doesn't care. She'll give it a go, but any unkindness will be water off a ducks back. She will not take it to heart and won't take it too seriously.
(I just knew she would get Anton. He must have been one bad boy in a past life.)
