Fundraisers across the county will be taking part in the weird and wacky to raise money for Children in Need.
The BBC fundraising bonanza takes place today and people young and old are holding events in the run up to the main event.
Children at Westgate Academy in Lincoln are staging a range of events to raise money.
They will be going to school in spotty clothes, playing name the bear, holding cake sales and decorating the building in spots.
Anna Cross, deputy head, said: "All the children will be given a coloured piece of card to decorate the outside of the school.
"The whole building will be covered in red, blue, green and yellow spots as high as the children can reach.
"The school council have put a lot of work into how we can raise money for Children in Need and everybody is now really looking forward to Friday.
"We usually raise between £800 and £900 so hopefully we can manage to do that again this year."
Since Children in Need started in 1980, over £600 million has been raised.
This year, two Lincoln choirs will be taking part in a concert.
Harmony Lincs and Ling Moor Primary School Choir will perform at the sing for Pudsey concert at Baths Hall, Scunthorpe, on Friday evening.
BBC Look North will also be presenting the region's broadcasts on the main BBC1 show from the concert.
Tony Chapman, chorus director, said: "We are very much looking forward to it.
"It is for a brilliant cause so hopefully we can help raise lots of money."
Tickets, priced £10 adults and £9 concessions, are available from the Baths Hall by calling 0844 854 2776.
All proceeds go directly to Children in Need.
Doors open at 6pm and the concert starts at 7pm.
Last year, Echo sports editor John Pakey completed a 1,000km bike ride, raising around £35,000for the charity.
He joined BBC Radio Lincolnshire's Rod Whiting and Louise Wheeler in riding from Neustadt in Germany to Lincoln.
"The ride was easily the hardest physical and mental challenge I've ever undertaken, and I've run marathons," he said.
"At times it was hard to get through, but knowing it was for a good cause meant there was never a question of quitting.
"It was horrible, but I would do it all over again.
"I would say to anyone doing any fundraising this year good luck and know that for whatever pain, discomfort or embarrassment they might be putting themselves through, it is all for a brilliant and worthy cause."
