The Mugnum is a quiz held at the annual reunion, with the questions being set by members attending the function.
The traditional prize is a mug. However since 2001 a piece of Venetian glass mounted on a wooden base, has also been awarded to the winner.
The trophy was presented to the club by Peter Chitty, a 1987 contender. Peter served the Club for many years as Membership Secretary, until his death in 2011.
