'Witticism' was a British unrealised plan for a special forces raid by four men of the Small Scale Raiding Force who, with two canoes and limpet mines, were to be carried in one (originally two) motor gun boats of the 15^th Motor Gun Boat Flotilla to attack German vessels in the harbour of St Peter Port, the main town of Guernsey in the Channel islands group (7 December 1942/12 January 1943).

Schemed as the blueprint for a programme of similar raids on small ports along the coast of German-occupied Europe, 'Witticism' was postponed from its first date as a result of weather considerations, and finally cancelled as the Small Scale Raiding Force was disbanded.
