Get the Duffymug. Duffy or ‘Duffball’ as he is better known (apparently it’s because he has only one testicle) is the class joker. He is a complete legend and tells all the best jokes, although most of them are pretty bad. His most commonly used words are wasteman, big-man and Dracula. His most common catchphrase is ‘Glyn is a G’.
