Our weekly round-up of outlandish and interesting information collected from the corners of the charity sector.

Nut roast-loving, Guardian-reading lefties

So the nation has, as a whole, been transfixed with the brilliance of the YouGov profiler, which allows you find out almost anything you might want to know about people interested in a particular thing – a film, or an idea, or a place or person. Including charity.

So what does the typical charity supporter look like? You can find out exactly here, but let’s sum up.

You won't be surprised.

It seems people who like charity also lean so heavily to the left politically that Karl Marx is getting annoyed at having to prop them up.

Perhaps unsurprisingly this group are also Guardian readers.

When not reading the Guardian, they enjoy sailing, writing, pottery, singing, looking after their cat and enjoying a range of vegetarian food, mainly nut roasts and occasionally sheep’s yogurt.

Yeah, but they’ve got fewer tanks

Paula Sussex, chief executive of the Charity Commission, is, like YouGov, fond of statistics, and she reached for another one to explain the prevalence of the sector in this country.

“The number of volunteers in the UK is greater than the number of soldiers in the People’s Liberation Army of China,” she said.

The PLA is, famously, the world’s largest employer, with the Indian railways in second place, and our very own NHS third.

Fair enough, UK volunteers may outnumber the PLA. But I still reckon they’d lose if it came to a fight.

The best toilet joke in the world

So WaterAid have, after an intensive competition,  announced the nation’s favourite toilet joke.

It’s a good one, too, from comedian Bec Hill:

"For Christmas last year I got given Sudoku toilet paper. It’s useless. You can only fill it in with number ones and number twos.”

In second place was Matt Forde with this classic: “Did you hear about the film Constipated? It never came out.”

In Diary’s opinion there is a better gag, too, by John Cooper Clarke, but you need a bit of time on you hands to listen to it. Maybe don't do it at work, either.

The competition was part of a campaign to remind people that one in three people in the world have nowhere safe, clean and private to poo. Which is, as the charity says, no joke.

Wanted: Guide Dogs fundraiser, 20:20 vision essential

Following the Dispatches report exposing incidents of poor practice at telephone fundraising companies you might think they would all be on their best behaviour for at least a few months. Not so, it seems. Ethicall has been accused of sacking a fundraiser for Guide Dogs because she has a visual impairment.

Zoe Goodman turned up to persuade people to support a charity for blind people, and presumably felt that limited sight might be an advantage. Not so. She told Mail Online that she felt “shocked, bullied and patronised” after she asked Ethicall to get software to magnify her screen and they instead told her not to bother coming back.

Ethicall claim the software she needed was not compatible with their systems and Guide Dogs has said it is investigating. Diary hopes this investigation is being carried out with the aid of a sniffer dog but rather suspects that dogs are banned from Ethicall’s premises on health and safety grounds.
