Staying with the theme of fun with biscuits we have Biscuit Throwing
The one biscuit you should never pick if you enter a dunking competition, the humble Rich Tea, is the very one chosen for its aerodynamic properties in Biscuit Throwing. The World Biscuit Throwing Championships, an irregularly held charity event, were first held at the 2002 Glendale Show, Northumberland. Contestants have three attempts to propel a rich tea the furthest distance (the winning distance was 80m) in the hope of securing the trophy... a varnished Rich Tea.
You can't help but feel the organisers have missed a trick here. If they included the Chocolate Eclair Javelin and Chelsea Bun Shot Put they would have the full complement of field throwing events.
