Duffy

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’.

Oi, Duffy stop giving me bare jest, your making me skeet in my pants!

One case of this breed of Duffy is known by many in a small area of northern England (Radcliffe). Treat with caution.
