Lance Corporal Jack Jones is a fictional Home Guard platoon lance corporal and veteran of the British Empire, first portrayed by Clive Dunn in the BBC television sitcom Dad's Army. His catchphrases are "Don't panic!", "Permission to speak, sir?" and "They don't like it up 'em!". Jones also often recounts his past military experiences particularly those in Sudan and India and gives a glimpse to the military traditions and events in the concluding years of the 19th century.
