Youngsters embraced their silly side to raise almost £1,300 for Comic Relief.
They also snapped up a joke book, all the gags for which had been submitted by children at the school in Denbigh Road.
Sales of cakes and pizzas on the day helped boost the total raised for Comic Relief, which supports good causes in the UK and overseas.
As well as featuring pupils' favourite rib-ticklers the joke book, which is still on sale at the school, is packed with photos of teachers sporting ridiculous costumes in the name of charity.
The school's welfare and resources officer Mani Jaga said: "Everyone had great fun on the day and we're delighted with how much we've raised."
