Vic and Bob had no idea what George Dawes (Matt Lucas) was going to say when giving the scores.
Matt Lucas was discovered by Bob Mortimer at a club and asked Matt Lucas to play George Dawes, the scorekeeper in the show. It was Matt Luca's idea for George Dawes to wear a romper-suit, instead of just a nappy.
Vic Reeves slipping over on the dove poo in (#3.7) was not in the script and you can tell by Bob Mortimer's reaction which was genuine, Mortimer improvised the line "That bad bird is full of dirt!".
Bob Mortimer admitted in an interview that the reason why he often made fun of Ulrika Johnson on the show was because he fancied her.
Most of the show is unrehearsed.
