|Big Brother is getting fed up with the house being so miserable lately...
He has set Helen a secret task to fix that - by turning her into Hilarious Helen for the day.
She has been tasked with making every single housemates smile, whether it's by playing silly pranks or telling them corny jokes.
Mostly, though, she'll be making them laugh at her expense, by telling self-deprecating stories or doing pratfalls.
Will they dare laugh at her? Hilarious Helen might have her work cut out for her.
Here is some of the jokes that Big Brother will be supplying Helen with:
What happened when the owl lost his voice?
Which dog needs contact lenses?
What happens when a duck flies upside down?
What kind of shoes do frogs like?
Will Helen pass her secret task and make ALL of the housemates laugh? Let us know what you think in the forum...
