Today's task is a classic battle of the sexes in the not-so-classic Keep Your Head Up.

Husband and wife will be divided as Heidi and Spencer act as team captains to their genders. Each team will then compete in a series of endurance challenges requiring them to keep their heads perfectly still whilst being tormented by a variety of ghoulish surprises. Think fake spiders and deranged dentists. Is it Halloween in a parallel universe or something?

The teams will sit with only their heads visible above a black cover. The housemates have to refrain from ducking, jerking their heads or turning their faces away at any time. Each twist of the head will earn the team a fail. The team who scores the fewest fails overall will win today's task.

Heidi and Spencer will dodge the grimmest parts, taking part from the Diary Room where they will be selecting from a range of visitors and distractions. Nice work if you can get it.

The team who keep their heads up most consistently will be treated to a reward later today. And the losing one, well... as the red queen in Alice in Wonderland was so fond of yelling: "Off with their heads" (not really).
