April Fools' Day was a holiday celebrated on 1 April. On this day it was customary for people to play practical jokes and hoaxes on one another.

On 1 April 1963, Ian Chesterton sent one of his Coal Hill School students, Little Titch Critchley, to the supplies cupboard for "a left-handed blackboard rubber". Later that morning, Ian started a snowball fight with Mr Okehurst, shouting, "April fool!" That afternoon, when John Brent tried to tell his father about the snowmen which had been animated by the Cold, Captain Brent thought his son was playing an April Fools' joke. (PROSE: Time and Relative)

When Harold sent a distress call warning Deimos Moonbase about a group of Ice Warriors taking over the tourist shuttle, Gregson Grenville responded, "Yeah, yeah. Very funny, Luigi. Happy April Fools to you too." (AUDIO: Deimos)
